The government of the Xinjiang -# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as -# local governments such as the Ürümqi city government use both times in -# publications, referring to what is popularly called Xinjiang time as -# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language -# they almost invariably use Xinjiang time. -# -# (Their ethnic Han compatriots would typically have no clue of its -# widespread use, however, because so extremely few of them are fluent in -# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) -# -# (...As with the rest of China there was a brief interval ending in 1990 -# or 1991 when summer time was in use.

Likewise for Kashgar and the rest of south Xinjiang I don't know of any -# start date for Xinjiang time. -# -# Without having access to local historical records, nor the ability to legally -# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur -# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also -# not be using Beijing time, but some local time.) - -# From David Cochrane (2014-03-26): -# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986: -# https://content.time.com/time/magazine/article/0,9171,960684,00.html - -# From Luther Ma (2014-04-22): -# I have interviewed numerous people of various nationalities and from -# different localities in Xinjiang and can confirm the information in Guo's -# report regarding Xinjiang, as well as the Time article reference by David -# Cochrane. Whether officially recognized or not (and both are officially -# recognized), two separate times have been in use in Xinjiang since at least -# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time; -# and Beijing Time. There is no confusion in Xinjiang as to which name refers -# to which time. Both are widely used in the province, although in some -# population groups might be use one to the exclusion of the other. The only -# problem is that computers and smart phones list Ürümqi (or Kashgar) as -# having the same time as Beijing. - -# From Paul Eggert (2014-06-30): -# In the early days of the PRC, Tibet was given its own time zone (UT +06) -# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun, -# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN -# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x. -# As this is before our 1970 cutoff, Tibet doesn't need a separate zone. -# -# Xinjiang Time is well-documented as being officially recognized.

Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using -# the time at 135E (GMT+9) -# -# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan -# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands, -# as well as Yaeyama and Miyako islands, adopted a new time zone called -# Western Standard Time, which is in GMT+8. -# -# 3.

Major -# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and -# East Jerusalem. -# -# Both areas were occupied by Israel in June 1967, but not annexed (except -# for East Jerusalem). They were on Israel time since then; there might -# have been a Military Governor's order about time zones, but I'm not aware -# of any (such orders may have been issued semi-annually whenever summer -# time was in effect, but maybe the legal aspect of time was just neglected). -# -# The Palestinian Authority was established in 1993, and got hold of most -# towns in the West Bank and Gaza by 1995.

Richard P Hunt, in "Islam city yielding to -# modern times", New York Times (1961-04-09), p 20, wrote that only airlines -# observed standard time, and that people in Jeddah mostly observed quasi-solar -# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12 -# o'clock for "Arab" time). -# -# Timekeeping differed depending on who you were and which part of Saudi -# Arabia you were in. In 1969, Elias Antar wrote that although a common -# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset - -# which meant that the time on one side of a mountain could differ greatly from -# the time on the other side - many foreigners set their watches to 6pm -# instead, while airlines instead used UTC +03 (except in Dhahran, where they -# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line -# Company used Aramco time in eastern Saudi Arabia and airline time in western. -# (The American Military Aid Advisory Group used plain UTC.) Antar writes, -# "A man named Higgins, so the story goes, used to run a local power -# station. One day, the whole thing became too much for Higgins and he -# assembled his staff and laid down the law. 'I've had enough of this,' he -# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is -# going to run on Higgins Time.' And so, until last year, it did." See: -# Antar E. Dinner at When?

Now by a happy coincidence, 'summer' -# and 'standard' happen to start with the same letter; hence, the -# abbreviation does _not_ change... -# The legislation does not actually define abbreviations, at least -# in this State, but the abbreviation is just commonly taken to be the -# initials of the phrase, and the legislation here uniformly uses -# the phrase 'summer time' and does not use the phrase 'daylight -# time'. -# Announcers on the Commonwealth radio network, the ABC (for Australian -# Broadcasting Commission), use the phrases 'Eastern Standard Time' -# or 'Eastern Summer Time'. (Note, though, that as I say in the -# current australasia file, there is really no such thing.) Announcers -# on its overseas service, Radio Australia, use the same phrases -# prefixed by the word 'Australian' when referring to local times; -# time announcements on that service, naturally enough, are made in UTC. - -# From Paul Eggert (2014-06-30): -# -# Inspired by Mackin's remarks quoted above, earlier versions of this -# file used "EST" for both Eastern Standard Time and Eastern Summer -# Time in Australia, and similarly for "CST", "CWST", and "WST". -# However, these abbreviations were confusing and were not common -# practice among Australians, and there were justifiable complaints -# about them, so I attempted to survey current Australian usage. -# For the tz database, the full English phrase is not that important; -# what matters is the abbreviation. It's difficult to survey the web -# directly for abbreviation usage, as there are so many false hits for -# strings like "EST" and "EDT", so I looked for pages that defined an -# abbreviation for eastern or central DST in Australia, and got the -# following numbers of unique hits for the listed Google queries: -# -# 10 "Eastern Daylight Time AEST" site:au [some are false hits] -# 10 "Eastern Summer Time AEST" site:au -# 10 "Summer Time AEDT" site:au -# 13 "EDST Eastern Daylight Saving Time" site:au -# 18 "Summer Time ESST" site:au -# 28 "Eastern Daylight Saving Time EDST" site:au -# 39 "EDT Eastern Daylight Time" site:au [some are false hits] -# 53 "Eastern Daylight Time EDT" site:au [some are false hits] -# 54 "AEDT Australian Eastern Daylight Time" site:au -# 182 "Eastern Daylight Time AEDT" site:au -# -# 17 "Central Daylight Time CDT" site:au [some are false hits] -# 46 "Central Daylight Time ACDT" site:au -# -# I tried several other variants (e.g., "Eastern Summer Time EST") but -# they all returned fewer than 10 unique hits. I also looked for pages -# mentioning both "western standard time" and an abbreviation, since -# there is no WST in the US to generate false hits, and found: -# -# 156 "western standard time" AWST site:au -# 226 "western standard time" WST site:au -# -# I then surveyed the top ten newspapers in Australia by circulation as -# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" -# and obtaining estimated counts from the initial page of search results. -# All ten papers greatly preferred "AEDT" to "EDT". The papers -# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, -# The Sydney Morning Herald, The West Australian, The Age, The Advertiser, -# The Australian, The Financial Review, and The Herald (Newcastle). -# -# I also searched for historical usage, to see whether abbreviations -# like "AEDT" are new. A Trove search -# found only one newspaper (The Canberra Times) with a house style -# dating back to the 1970s, I expect because other newspapers weren't -# fully indexed. The Canberra Times strongly preferred abbreviations -# like "AEDT". The first occurrence of "AEDT" was a World Weather -# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column -# (1993-01-24, p 16). The style was the typical usage but was not -# strictly enforced; for example, "Welcome to the twilight zones ..." -# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and -# WST, and goes on to say, "The confusion and frustration some feel -# about the lack of uniformity among Australia's six states and two -# territories has prompted one group to form its very own political -# party -- the Sydney-based Daylight Saving Extension Party." -# -# I also surveyed federal government sources.

The date is -# governed by the IDL; therefore, even on the high seas, there may be some -# places as late as fourteen hours later than UTC. And, since the IDL is not -# an international standard, there are some places on the high seas where the -# correct date is ambiguous. - -# From Wikipedia (2005-08-31): -# Before 1920, all ships kept local apparent time on the high seas by setting -# their clocks at night or at the morning sight so that, given the ship's -# speed and direction, it would be 12 o'clock when the Sun crossed the ship's -# meridian (12 o'clock = local apparent noon). During 1917, at the -# Anglo-French Conference on Time-keeping at Sea, it was recommended that all -# ships, both military and civilian, should adopt hourly standard time zones -# on the high seas. Whenever a ship was within the territorial waters of any -# nation it would use that nation's standard time. The captain was permitted -# to change his ship's clocks at a time of his choice following his ship's -# entry into another zone time - he often chose midnight.

There was a photo -# and a sketch map showing some of the sightlines involved. One paragraph -# of the text said: -# -# 'An old stone obelisk marking a forgotten terrestrial meridian stands -# beside the river at Kew. In the 18th century, before time and longitude -# was standardised by the Royal Observatory in Greenwich, scholars observed -# this stone and the movement of stars from Kew Observatory nearby. They -# made their calculations and set the time for the Horse Guards and Parliament, -# but now the stone is obscured by scrubwood and can only be seen by walking -# along the towpath within a few yards of it.' -# -# I have a one inch to one mile map of London and my estimate of the stone's -# position is 51° 28' 30" N, 0° 18' 45" W. The longitude should -# be within about ±2". The Ordnance Survey grid reference is TQ172761. -# -# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] - -# From Paul Eggert (1993-11-18): -# -# Howse writes that Britain was the first country to use standard time. -# The railways cared most about the inconsistencies of local mean time, -# and it was they who forced a uniform time on the country. -# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) -# and was popularized by Abraham Follett Osler (1808-1903). -# The first railway to adopt London time was the Great Western Railway -# in November 1840; other railways followed suit, and by 1847 most -# (though not all) railways used London time. On 1847-09-22 the -# Railway Clearing House, an industry standards body, recommended that GMT be -# adopted at all stations as soon as the General Post Office permitted it. -# The transition occurred on 12-01 for the L&NW, the Caledonian, -# and presumably other railways; the January 1848 Bradshaw's lists many -# railways as using GMT. By 1855 the vast majority of public -# clocks in Britain were set to GMT (though some, like the great clock -# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, -# one for local time and one for GMT). The last major holdout was the legal -# system, which stubbornly stuck to local time for many years, leading -# to oddities like polls opening at 08:13 and closing at 16:13. -# The legal system finally switched to GMT when the Statutes (Definition -# of Time) Act took effect; it received the Royal Assent on 1880-08-02. -# -# In the tables below, we condense this complicated story into a single -# transition date for London, namely 1847-12-01. We don't know as much -# about Dublin, so we use 1880-08-02, the legal transition time. - -# From Paul Eggert (2014-07-19): -# The ancients had no need for daylight saving, as they kept time -# informally or via hours whose length depended on the time of year. -# Daylight saving time in its modern sense was invented by the -# New Zealand entomologist George Vernon Hudson (1867-1946), -# whose day job as a postal clerk led him to value -# after-hours daylight in which to pursue his research. -# In 1895 he presented a paper to the Wellington Philosophical Society -# that proposed a two-hour daylight-saving shift. See: -# Hudson GV.

On the south face of the monolith, -# designed by G. W. Miller, is the William Willett Memorial Sundial, -# which is permanently set to Summer Time. - -# From Winston Churchill (1934-04-28): -# It is one of the paradoxes of history that we should owe the boon of -# summer time, which gives every year to the people of this country -# between 160 and 170 hours more daylight leisure, to a war which -# plunged Europe into darkness for four years, and shook the -# foundations of civilization throughout the world. -# -- "A Silent Toast to William Willett", Pictorial Weekly; -# republished in Finest Hour (Spring 2002) 1(114):26 -# https://www.winstonchurchill.org/publications/finest-hour/finest-hour-114/a-silent-toast-to-william-willett-by-winston-s-churchill - -# From Paul Eggert (2015-08-08): -# The OED Supplement says that the English originally said "Daylight Saving" -# when they were debating the adoption of DST in 1908; but by 1916 this -# term appears only in quotes taken from DST's opponents, whereas the -# proponents (who eventually won the argument) are quoted as using "Summer". -# The term "Summer Time" was introduced by Herbert Samuel, Home Secretary; see: -# Viscount Samuel.

Myers (2000-10-03): -# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir -# Alexander Maxwell of the Home Office asking whether there was any -# official designation; the reply of the 21st was that there wasn't -# but he couldn't think of anything better than the "Double British -# Summer Time" that the BBC had been using informally. -# https://www.polyomino.org.uk/british-time/bbc-19410418.png -# https://www.polyomino.org.uk/british-time/ho-19410421.png - -# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): -# [N]o official designation has as far as I know been adopted for the time -# which is to be introduced in May.... -# I cannot think of anything better than "Double British Summer Time" -# which could not be said to run counter to any official description. - -# From Paul Eggert (2000-10-02): -# Howse writes (p 157) 'DBST' too, but 'BDST' seems to have been common -# and follows the more usual convention of putting the location name first, -# so we use 'BDST'. - -# Peter Ilieve (1998-04-19) described at length -# the history of summer time legislation in the United Kingdom. -# Since 1998 Joseph S.

For example: -# -# "Timeball on the ballast office is down. Dunsink time." -# -- James Joyce, Ulysses -# -# The abbreviation DMT stood for "Dublin Mean Time" or "Dunsink Mean Time"; -# this being Ireland, opinions differed. -# -# Whitman says Dublin/Dunsink Mean Time was UT-00:25:21, which agrees -# with measurements of recent visitors to the Meridian Room of Dunsink -# Observatory; see Malone D. Dunsink and timekeeping. 2016-01-24. -# . Malone -# writes that the Nautical Almanac listed UT-00:25:22 until 1896, when -# it moved to UT-00:25:21.1 (I confirmed that the 1893 edition used -# the former and the 1896 edition used the latter). Evidently the -# news of this change propagated slowly, as Milne 1899 still lists -# UT-00:25:22 and cites the International Telegraph Bureau. As it is -# not clear that there was any practical significance to the change -# from UT-00:25:22 to UT-00:25:21.1 in civil timekeeping, omit this -# transition for now and just use the latter value, omitting its -# fraction since our format cannot represent fractions. - -# "Countess Markievicz ... claimed that the [1916] abolition of Dublin Mean Time -# was among various actions undertaken by the 'English' government that -# would 'put the whole country into the SF (Sinn Féin) camp'.

I spoke this morning with the Secretary of the Department of -# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is -# "Irish Summer Time", abbreviated to "IST". -# -# From Paul Eggert (2017-12-07): -# The 1996 anonymous contributor's goal was to determine the correct -# abbreviation for summer time in Dublin and so the contributor -# focused on the "IST", not on the "Irish Summer Time". Though the -# "IST" was correct, the "Irish Summer Time" appears to have been an -# error, as Ireland's Standard Time (Amendment) Act, 1971 states that -# standard time in Ireland remains at UT +01 and is observed in -# summer, and that Greenwich mean time is observed in winter. (Thanks -# to Derick Rethans for pointing out the error.) That is, when -# Ireland amended the 1968 act that established UT +01 as Irish -# Standard Time, it left standard time unchanged and established GMT -# as a negative daylight saving time in winter. So, in this database -# IST stands for Irish Summer Time for timestamps before 1968, and for -# Irish Standard Time after that.

Svalbard was declared -# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan -# Mayen by law of 1930-02-27 no 2, section 2. (From -# and -# ). The law/regulation -# for normal/standard time in Norway is from 1894-06-29 no 1 (came -# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a -# part of this law since 1925/1930. (From -# ) I have not been -# able to find if Jan Mayen used a different time zone (e.g. -0100) -# before 1930. Jan Mayen has only been "inhabited" since 1921 by -# Norwegian meteorologists and maybe used the same time as Norway ever -# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since -# before 1895, and therefore probably changed the local time somewhere -# between 1895 and 1925 (inclusive). - -# From Paul Eggert (2013-09-04): -# -# Actually, Jan Mayen was never occupied by Germany during World War II, -# so it must have diverged from Oslo time during the war, as Oslo was -# keeping Berlin time. -# -# says that the meteorologists -# burned down their station in 1940 and left the island, but returned in -# 1941 with a small Norwegian garrison and continued operations despite -# frequent air attacks from Germans. In 1943 the Americans established a -# radiolocating station on the island, called "Atlantic City". Possibly -# the UT offset changed during the war, but I think it unlikely that -# Jan Mayen used German daylight-saving rules. -# -# Svalbard is more complicated, as it was raided in August 1941 by an -# Allied party that evacuated the civilian population to England (says -# ).

Less 12 minutes gives the -# national standard time as 01:00:14 ahead of GMT.... -# -# About the beginning of CET in Sweden. The lawtext ("Svensk -# författningssamling 1899, no 44") states, that "from the beginning -# of 1900... ... the same as the mean solar time for the meridian at -# the distance of one hour of time from the meridian of the English -# observatory at Greenwich, or at 12 minutes 14 seconds to the west -# from the meridian of the Observatory of Stockholm". The law is dated -# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time -# in Sweden is 01:00:00 ahead of GMT. -# -# 1916: The lawtext ("Svensk författningssamling 1916, no 124") states -# that "1916-05-15 is considered to begin one hour earlier".

Between 1848 and 1894 Geneva did not -# follow Bern Mean Time but kept its own local mean time. -# To represent this, an extra zone would be needed. -# -# From Alois Treindl (2013-09-11): -# The Federal regulations say -# https://www.admin.ch/opc/de/classified-compilation/20071096/index.html -# ... the meridian for Bern mean time ... is 7° 26' 22.50". -# Expressed in time, it is 0h29m45.5s. - -# From Pierre-Yves Berger (2013-09-11): -# the "Circulaire du conseil fédéral" (December 11 1893) -# http://www.amtsdruckschriften.bar.admin.ch/viewOrigDoc.do?id=10071353 -# clearly states that the [1894-06-01] change should be done at midnight -# but if no one is present after 11 at night, could be postponed until one -# hour before the beginning of service. - -# From Paul Eggert (2013-09-11): -# Round BMT to the nearest even second, 0:29:46. -# -# We can find no reliable source for Shanks's assertion that all of Switzerland -# except Geneva switched to Bern Mean Time at 00:00 on 1848-09-12.

The timekeeping it gives the -# most detail for is postal and telegraph time: here, federal legislation (the -# "Bundesgesetz über die Erstellung von elektrischen Telegraphen") passed on -# 1851-11-23, and an official implementation notice was published 1853-07-16 -# (Bundesblatt 1853, Bd.

His 1870 proposal was based on Washington, DC, -# but in 1872-05 he moved the proposed origin to Greenwich. - -# From Paul Eggert (2018-03-20): -# Dowd's proposal left many details unresolved, such as where to draw -# lines between time zones. The key individual who made time zones -# work in the US was William Frederick Allen - railway engineer, -# managing editor of the Travelers' Guide, and secretary of the -# General Time Convention, a railway standardization group. Allen -# spent months in dialogs with scientific and railway leaders, -# developed a workable plan to institute time zones, and presented it -# to the General Time Convention on 1883-04-11, saying that his plan -# meant "local time would be practically abolished" - a plus for -# railway scheduling. By the next convention on 1883-10-11 nearly all -# railroads had agreed and it took effect on 1883-11-18. That Sunday -# was called the "day of two noons", as some locations observed noon -# twice. Allen witnessed the transition in New York City, writing: -# -# I heard the bells of St. Paul's strike on the old time. Four -# minutes later, obedient to the electrical signal from the Naval -# Observatory ... the time-ball made its rapid descent, the chimes -# of old Trinity rang twelve measured strokes, and local time was -# abandoned, probably forever. -# -# Most of the US soon followed suit.

(1991). -# Make sure you have the errata sheet; the book is somewhat useless without it. -# It is the source for most of the pre-1991 US entries below. - -# From Paul Eggert (2001-03-06): -# Daylight Saving Time was first suggested as a joke by Benjamin Franklin -# in his whimsical essay "An Economical Project for Diminishing the Cost -# of Light" published in the Journal de Paris (1784-04-26). -# Not everyone is happy with the results: -# -# I don't really care how time is reckoned so long as there is some -# agreement about it, but I object to being told that I am saving -# daylight when my reason tells me that I am doing nothing of the kind. -# I even object to the implication that I am wasting something -# valuable if I stay in bed after the sun has risen. As an admirer -# of moonlight I resent the bossy insistence of those who want to -# reduce my time for enjoying it. At the back of the Daylight Saving -# scheme I detect the bony, blue-fingered hand of Puritanism, eager -# to push people into bed earlier, and get them up earlier, to make -# them healthy, wealthy and wise in spite of themselves. -# -# -- Robertson Davies, The diary of Samuel Marchbanks, -# Clarke, Irwin (1947), XIX, Sunday -# -# For more about the first ten years of DST in the United States, see -# Robert Garland, Ten years of daylight saving from the Pittsburgh standpoint -# (Carnegie Library of Pittsburgh, 1927). -# http://www.clpgh.org/exhibit/dst.html -# -# Shanks says that DST was called "War Time" in the US in 1918 and 1919. -# However, DST was imposed by the Standard Time Act of 1918, which -# was the first nationwide legal time standard, and apparently -# time was just called "Standard Time" or "Daylight Saving Time". - -# From Arthur David Olson: -# US Daylight Saving Time ended on the last Sunday of *October* in 1974. -# See, for example, the front page of the Saturday, 1974-10-26 -# and Sunday, 1974-10-27 editions of the Washington Post. - -# From Arthur David Olson: -# Before the Uniform Time Act of 1966 took effect in 1967, observance of -# Daylight Saving Time in the US was by local option, except during wartime. - -# From Arthur David Olson (2000-09-25): -# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama. -# In the introduction, Oboler spoke of "Eastern Peace Time." -# An AltaVista search turned up: -# https://web.archive.org/web/20000926032210/http://rowayton.org/rhs/hstaug45.html -# "When the time is announced over the radio now, it is 'Eastern Peace -# Time' instead of the old familiar 'Eastern War Time.'

Douglas, _The Early Days of Radio Broadcasting_ (1987): -# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set -# to switch to London for Attlee's address, but the American people -# never got to hear his speech live. According to one press account, -# CBS' Bob Trout was first to announce the word of Japan's surrender, -# but a few seconds later, NBC, ABC and Mutual also flashed the word -# of surrender, all of whom interrupting the bells of Big Ben in -# London which were to precede Mr. Attlee's speech. - -# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout. From -# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times: -# -# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender. -# Any announcement from Asia would reach St. John's New York newsroom on a -# wire service teletype machine, which had prescribed signals for major news. -# Associated Press, for example, would ring five bells before spewing out -# typed copy of an important story, and 10 bells for news "of transcendental -# importance." -# -# On Aug. 14, stalling while talking steadily into the NBC networks' open -# microphone, St. John heard five bells and waited only to hear a sixth bell, -# before announcing confidently: "Ladies and gentlemen, World War II is over. -# The Japanese have agreed to our surrender terms." -# -# He had scored a 20-second scoop on other broadcasters. - -# From Arthur David Olson (2005-08-22): -# Paul has been careful to use the "US" rules only in those locations -# that are part of the United States; this reflects the real scope of -# U.S. government action.

In 1965 a provincial -# referendum favoured legislating common time practices. -# -# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of -# Saskatchewan 1978) was proclaimed, and established that the eastern -# part of Saskatchewan would use CST year round, that districts in -# northwest Saskatchewan would by default follow CST but could opt to -# follow Mountain Time rules (thus 1 hour difference in the winter and -# zero in the summer), and that districts in southwest Saskatchewan would -# by default follow MT but could opt to follow CST. -# -# It took a few years for the dust to settle (I know one story of a town -# on one time zone having its school in another, such that a mom had to -# serve her family lunch in two shifts), but presently it seems that only -# a few towns on the border with Alberta (e.g. Lloydminster) follow MT -# rules any more; all other districts appear to have used CST year round -# since sometime in the 1960s. - -# From Chris Walton (2006-06-26): -# The Saskatchewan time act which was last updated in 1996 is about 30 pages -# long and rather painful to read. -# http://www.qp.gov.sk.ca/documents/English/Statutes/Statutes/T14.pdf - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Regina 1918 only - Apr 14 2:00 1:00 D -Rule Regina 1918 only - Oct 27 2:00 0 S -Rule Regina 1930 1934 - May Sun>=1 0:00 1:00 D -Rule Regina 1930 1934 - Oct Sun>=1 0:00 0 S -Rule Regina 1937 1941 - Apr Sun>=8 0:00 1:00 D -Rule Regina 1937 only - Oct Sun>=8 0:00 0 S -Rule Regina 1938 only - Oct Sun>=1 0:00 0 S -Rule Regina 1939 1941 - Oct Sun>=8 0:00 0 S -Rule Regina 1942 only - Feb 9 2:00 1:00 W # War -Rule Regina 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Regina 1945 only - Sep lastSun 2:00 0 S -Rule Regina 1946 only - Apr Sun>=8 2:00 1:00 D -Rule Regina 1946 only - Oct Sun>=8 2:00 0 S -Rule Regina 1947 1957 - Apr lastSun 2:00 1:00 D -Rule Regina 1947 1957 - Sep lastSun 2:00 0 S -Rule Regina 1959 only - Apr lastSun 2:00 1:00 D -Rule Regina 1959 only - Oct lastSun 2:00 0 S -# -Rule Swift 1957 only - Apr lastSun 2:00 1:00 D -Rule Swift 1957 only - Oct lastSun 2:00 0 S -Rule Swift 1959 1961 - Apr lastSun 2:00 1:00 D -Rule Swift 1959 only - Oct lastSun 2:00 0 S -Rule Swift 1960 1961 - Sep lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Regina -6:58:36 - LMT 1905 Sep - -7:00 Regina M%sT 1960 Apr lastSun 2:00 - -6:00 - CST -Zone America/Swift_Current -7:11:20 - LMT 1905 Sep - -7:00 Canada M%sT 1946 Apr lastSun 2:00 - -7:00 Regina M%sT 1950 - -7:00 Swift M%sT 1972 Apr lastSun 2:00 - -6:00 - CST - - -# Alberta - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Edm 1918 1919 - Apr Sun>=8 2:00 1:00 D -Rule Edm 1918 only - Oct 27 2:00 0 S -Rule Edm 1919 only - May 27 2:00 0 S -Rule Edm 1920 1923 - Apr lastSun 2:00 1:00 D -Rule Edm 1920 only - Oct lastSun 2:00 0 S -Rule Edm 1921 1923 - Sep lastSun 2:00 0 S -Rule Edm 1942 only - Feb 9 2:00 1:00 W # War -Rule Edm 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Edm 1945 only - Sep lastSun 2:00 0 S -Rule Edm 1947 only - Apr lastSun 2:00 1:00 D -Rule Edm 1947 only - Sep lastSun 2:00 0 S -Rule Edm 1967 only - Apr lastSun 2:00 1:00 D -Rule Edm 1967 only - Oct lastSun 2:00 0 S -Rule Edm 1969 only - Apr lastSun 2:00 1:00 D -Rule Edm 1969 only - Oct lastSun 2:00 0 S -Rule Edm 1972 1986 - Apr lastSun 2:00 1:00 D -Rule Edm 1972 2006 - Oct lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Edmonton -7:33:52 - LMT 1906 Sep - -7:00 Edm M%sT 1987 - -7:00 Canada M%sT - - -# British Columbia - -# From Paul Eggert (2006-03-22): -# Shanks & Pottenger write that since 1970 most of this region has -# been like Vancouver. -# Dawson Creek uses MST.

Igloolik [was similar but then] -# made the switch to central time on Saturday, Nov. 6. - -# From Paul Eggert (2000-10-02): -# Matthews and Vincent (1998) say the following, but we lack histories -# for these potential new Zones. -# -# The Canadian Forces station at Alert uses Eastern Time while the -# handful of residents at the Eureka weather station [in the Central -# zone] skip daylight savings.

I'm -# checking for more info, and will get back to you if I come up with -# more. -# [Also see (2001-03-09).] - -# From Gwillim Law (2005-05-21): -# According to ... -# http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp -# (from a 1998 Canadian Geographic article), the de facto and de jure time -# for Southampton Island (at the north end of Hudson Bay) is UTC-5 all year -# round. Using Google, it's easy to find other websites that confirm this. -# I wasn't able to find how far back this time regimen goes, but since it -# predates the creation of Nunavut, it probably goes back many years.... -# The Inuktitut name of Coral Harbour is Sallit, but it's rarely used. -# -# From Paul Eggert (2014-10-17): -# For lack of better information, assume that Southampton Island observed -# daylight saving only during wartime. Gwillim Law's email also -# mentioned maps now maintained by National Research Council Canada; -# see above for an up-to-date link. - -# From Chris Walton (2007-03-01): -# ... the community of Resolute (located on Cornwallis Island in -# Nunavut) moved from Central Time to Eastern Time last November. -# Basically the community did not change its clocks at the end of -# daylight saving.... -# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html - -# From Chris Walton (2011-03-21): -# Back in 2007 I initiated the creation of a new "zone file" for Resolute -# Bay. Resolute Bay is a small community located about 900km north of -# the Arctic Circle. The zone file was required because Resolute Bay had -# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007. -# -# According to new information which I received last week, Resolute Bay -# went back to using UTC-6 in the winter of 2007-2008... -# -# On March 11/2007 most of Canada went onto daylight saving. On March -# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I -# talked to somebody that was both knowledgeable and helpful. I was able -# to confirm that Resolute Bay was still operating on UTC-5. It was -# explained to me that Resolute Bay had been on the Eastern Time zone -# (EST) in the winter, and was now back on the Central Time zone (CDT). -# i.e. the time zone had changed twice in the last year but the clocks -# had not moved. The residents had to know which time zone they were in -# so they could follow the correct TV schedule... -# -# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I -# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature -# of the phone call, I decided to seek out an alternate source of -# information. I found an e-mail address for somebody by the name of -# Stephanie Adams whose job was listed as "Inns North Support Officer for -# Arctic Co-operatives." I was under the impression that Stephanie lived -# and worked in Resolute Bay... -# -# On March 14/2011 I phoned the hamlet office again. I was told that -# Resolute Bay had been using Central Standard Time over the winter of -# 2010-2011 and that the clocks had therefore been moved one hour ahead -# on March 13/2011. The person I talked to was aware that Resolute Bay -# had previously experimented with Eastern Standard Time but he could not -# tell me when the practice had stopped. -# -# On March 17/2011 I searched the Web to find an e-mail address of -# somebody that might be able to tell me exactly when Resolute Bay went -# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz -# used to be the mayor of Resolute Bay and he apparently owns half the -# businesses including "South Camp Inn." This website has some info on -# Aziz: -# http://www.uphere.ca/node/493 -# -# I sent Aziz an e-mail asking when Resolute Bay had stopped using -# Eastern Standard Time. -# -# Aziz responded quickly with this: "hi, The time was not changed for the -# 1 year only, the following year, the community went back to the old way -# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in -# the winter Zulu plus 6 hrs" -# -# This of course conflicted with everything I had ascertained in November 2008. -# -# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz -# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You -# may want to check with the weather office in Resolute Bay or do a -# search on the weather through Env. Canada. web site" -# -# If I had realized the Stephanie did not live in Resolute Bay I would -# never have contacted her. I now believe that all the information I -# obtained in November 2008 should be ignored... -# I apologize for reporting incorrect information in 2008. - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule NT_YK 1918 only - Apr 14 2:00 1:00 D -Rule NT_YK 1918 only - Oct 27 2:00 0 S -Rule NT_YK 1919 only - May 25 2:00 1:00 D -Rule NT_YK 1919 only - Nov 1 0:00 0 S -Rule NT_YK 1942 only - Feb 9 2:00 1:00 W # War -Rule NT_YK 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule NT_YK 1945 only - Sep 30 2:00 0 S -Rule NT_YK 1965 only - Apr lastSun 0:00 2:00 DD -Rule NT_YK 1965 only - Oct lastSun 2:00 0 S -Rule NT_YK 1980 1986 - Apr lastSun 2:00 1:00 D -Rule NT_YK 1980 2006 - Oct lastSun 2:00 0 S -Rule NT_YK 1987 2006 - Apr Sun>=1 2:00 1:00 D -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -# aka Panniqtuuq -Zone America/Pangnirtung 0 - -00 1921 # trading post est. - -4:00 NT_YK A%sT 1995 Apr Sun>=1 2:00 - -5:00 Canada E%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 Canada E%sT -# formerly Frobisher Bay -Zone America/Iqaluit 0 - -00 1942 Aug # Frobisher Bay est. - -5:00 NT_YK E%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 Canada E%sT -# aka Qausuittuq -Zone America/Resolute 0 - -00 1947 Aug 31 # Resolute founded - -6:00 NT_YK C%sT 2000 Oct 29 2:00 - -5:00 - EST 2001 Apr 1 3:00 - -6:00 Canada C%sT 2006 Oct 29 2:00 - -5:00 - EST 2007 Mar 11 3:00 - -6:00 Canada C%sT -# aka Kangiqiniq -Zone America/Rankin_Inlet 0 - -00 1957 # Rankin Inlet founded - -6:00 NT_YK C%sT 2000 Oct 29 2:00 - -5:00 - EST 2001 Apr 1 3:00 - -6:00 Canada C%sT -# aka Iqaluktuuttiaq -Zone America/Cambridge_Bay 0 - -00 1920 # trading post est.? - -7:00 NT_YK M%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 - EST 2000 Nov 5 0:00 - -6:00 - CST 2001 Apr 1 3:00 - -7:00 Canada M%sT -Zone America/Yellowknife 0 - -00 1935 # Yellowknife founded? - -7:00 NT_YK M%sT 1980 - -7:00 Canada M%sT -Zone America/Inuvik 0 - -00 1953 # Inuvik founded - -8:00 NT_YK P%sT 1979 Apr lastSun 2:00 - -7:00 NT_YK M%sT 1980 - -7:00 Canada M%sT -Zone America/Whitehorse -9:00:12 - LMT 1900 Aug 20 - -9:00 NT_YK Y%sT 1967 May 28 0:00 - -8:00 NT_YK P%sT 1980 - -8:00 Canada P%sT -Zone America/Dawson -9:17:40 - LMT 1900 Aug 20 - -9:00 NT_YK Y%sT 1973 Oct 28 0:00 - -8:00 NT_YK P%sT 1980 - -8:00 Canada P%sT - - -############################################################################### - -# Mexico - -# From Paul Eggert (2014-12-07): -# The Investigation and Analysis Service of the -# Mexican Library of Congress (MLoC) has published a -# history of Mexican local time (in Spanish) -# http://www.diputados.gob.mx/bibliot/publica/inveyana/polisoc/horver/index.htm -# -# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC. -# (In all cases we go with the MLoC.) -# S&P report that Baja was at -8:00 in 1922/1923. -# S&P say the 1930 transition in Baja was 1930-11-16. -# S&P report no DST during summer 1931. -# S&P report a transition at 1932-03-30 23:00, not 1932-04-01. - -# From Gwillim Law (2001-02-20): -# There are some other discrepancies between the Decrees page and the -# tz database.

-# So much for footnotes about Saudi Arabia.
-# Apparent noon times below are for Riyadh; your mileage will vary.
-# Times were computed using formulas in the U.S. Naval Observatory's
-# Almanac for Computers 1987; the formulas "will give EqT to an accuracy of
-# [plus or minus two] seconds during the current year."
-#
-# Rounding to the nearest five seconds results in fewer than
-# 256 different "time types"--a limit that's faced because time types are
-# stored on disk as unsigned chars.

-# Apparent noon times below are for Riyadh; they're a bit off for other places.
-# Times were computed using formulas in the U.S. Naval Observatory's
-# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
-# [plus or minus two] seconds during the current year."
-#
-# Rounding to the nearest five seconds results in fewer than

-# Apparent noon times below are for Riyadh; they're a bit off for other places.
-# Times were computed using a formula provided by the U. S. Naval Observatory:
-#	eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
-#		-12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
-#		+ 19.3 * cos(3 * l);
-# where l is the "mean longitude of the Sun" given by
-#	l = 279.642 degrees + 0.985647 * d
-# and d is the interval in days from January 0, 0 hours Universal Time
-# (equaling the day of the year plus the fraction of a day from zero hours).
-# The accuracy of the formula is plus or minus three seconds.
-#
-# Rounding to the nearest five seconds results in fewer than
-# 256 different "time types"--a limit that's faced because time types are
-# stored on disk as unsigned chars.

-# From Fabián L. Arce Jofré (2000-04-04):
-# The law that claimed DST for Argentina was derogated by President Fernando

-# ... this weekend, the Province of Tucumán decided it'd go back to UTC-03:00

-# From Gwillim Law (2004-06-14):
-# http://www.lanacion.com.ar/04/06/10/de_609078.asp ...
-#     "The time change in Tierra del Fuego was a conflicted decision from
-#   the start.  The government had decreed that the measure would take
-#   effect on June 1, but a normative error forced the new time to begin
-#   three days earlier, from a Saturday to a Sunday....
-# Our understanding was that the change was originally scheduled to take place
-# on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other
-# provinces).  Sunday was May 30, only two days earlier.  So the article
-# contains a contradiction.  I would give more credence to the Saturday/Sunday
-# date than the "three days earlier" phrase, and conclude that Tierra del
-# Fuego set its clocks back at 2004-05-30 00:00.
-#
-# From Steffen Thorsen (2004-10-05):
-# The previous law 7210 which changed the province of Mendoza's time zone

-# http://www.worldtimezone.com/dst_news/dst_news_argentina02.html
-
-# From Jesper Nørgaard Welen (2008-01-18):
-# The page of the San Luis provincial government
-# http://www.sanluis.gov.ar/notas.asp?idCanal=0&id=22812
-# confirms what Alex Krivenyshev has earlier sent to the tz
-# emailing list about that San Luis plans to return to standard
-# time much earlier than the rest of the country. It also
-# confirms that upon request the provinces San Juan and Mendoza
-# refused to follow San Luis in this change.
-#
-# The change is supposed to take place Monday the 21st at 0:00
-# hours. As far as I understand it if this goes ahead, we need
-# a new timezone for San Luis (although there are also documented
-# independent changes in the southamerica file of San Luis in
-# 1990 and 1991 which has not been confirmed).
-
-# From Jesper Nørgaard Welen (2008-01-25):
-# Unfortunately the below page has become defunct, about the San Luis
-# time change. Perhaps because it now is part of a group of pages "Most
-# important pages of 2008."
-#
-# You can use
-# http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
-# instead it seems. Or use "Buscador" from the main page of the San Luis
-# government, and fill in "huso" and click OK, and you will get 3 pages
-# from which the first one is identical to the above.
-
-# From Mariano Absatz (2008-01-28):
-# I can confirm that the Province of San Luis (and so far only that
-# province) decided to go back to UTC-3 effective midnight Jan 20th 2008
-# (that is, Monday 21st at 0:00 is the time the clocks were delayed back
-# 1 hour), and they intend to keep UTC-3 as their timezone all year round
-# (that is, unless they change their mind any minute now).
-#
-# So we'll have to add yet another city to 'southamerica' (I think San
-# Luis city is the mos populated city in the Province, so it'd be
-# America/Argentina/San_Luis... of course I can't remember if San Luis's
-# history of particular changes goes along with Mendoza or San Juan :-(
-# (I only remember not being able to collect hard facts about San Luis
-# back in 2004, when these provinces changed to UTC-4 for a few days, I
-# mailed them personally and never got an answer).
-
-# From Paul Eggert (2014-08-12):
-# Unless otherwise specified, data entries are from Shanks & Pottenger through
-# 1992, from the IATA otherwise.  As noted below, Shanks & Pottenger say that
-# America/Cordoba split into 6 subregions during 1991/1992, one of which
-# was America/San_Luis, but we haven't verified this yet so for now we'll
-# keep America/Cordoba a single region rather than splitting it into the
-# other 5 subregions.
-
-# From Mariano Absatz (2009-03-13):
-# Yesterday (with our usual 2-day notice) the Province of San Luis
-# decided that next Sunday instead of "staying" @utc-03:00 they will go
-# to utc-04:00 until the second Saturday in October...
-#
-# The press release is at
-# http://www.sanluis.gov.ar/SL/Paginas/NoticiaDetalle.asp?TemaId=1&InfoPrensaId=3102
-# (I couldn't find the decree, but www.sanluis.gov.ar
-# is the official page for the Province Government.)
-#
-# There's also a note in only one of the major national papers ...
-# http://www.lanacion.com.ar/nota.asp?nota_id=1107912
-#
-# The press release says [quick and dirty translation]:
-# ... announced that next Sunday, at 00:00, Puntanos (the San Luis
-# inhabitants) will have to turn back one hour their clocks
-#
-# Since then, San Luis will establish its own Province timezone. Thus,
-# during 2009, this timezone change will run from 00:00 the third Sunday
-# in March until 24:00 of the second Saturday in October.
-
-# From Mariano Absatz (2009-10-16):
-# ...the Province of San Luis is a case in itself.
-#
-# The Law at
-# http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaID=276
-# is ambiguous because establishes a calendar from the 2nd Sunday in
-# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
-# complement of that starting on the 2nd Sunday of March at 0:00 and
-# ending on the 2nd Saturday of March at 24:00.
-#
-# This clearly breaks every time the 1st of March or October is a Sunday.
-#
-# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
-# Sunday of October and March.
-#
-# The problem is that the changes in the rest of the Provinces that did
-# change in 2007/2008, were made according to the Federal Law and Decrees
-# that did so on the 3rd Sunday of October and March.
-#
-# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
-# (October 11th) at 0:00.
-#
-# So I guess a new set of rules, besides "Arg", must be made and the last
-# America/Argentina/San_Luis entries should change to use these...
-# ...
-
-# From Alexander Krivenyshev (2010-04-09):
-# According to news reports from El Diario de la República Province San
-# Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time
-# after April 11, 2010 - will continue to have same time as rest of
-# Argentina (UTC-3) (no DST).

-
-# From Mariano Absatz (2010-04-12):
-# yes...I can confirm this...and given that San Luis keeps calling
-# UTC-03:00 "summer time", we should't just let San Luis go back to "Arg"
-# rules...San Luis is still using "Western ARgentina Time" and it got
-# stuck on Summer daylight savings time even though the summer is over.
-
-# From Paul Eggert (2018-01-23):
-# Perhaps San Luis operates on the legal fiction that it is at -04
-# with perpetual daylight saving time, but ordinary usage typically seems to
-# just say it's at -03; see, for example,
-# https://es.wikipedia.org/wiki/Hora_oficial_argentina
-# We've documented similar situations as being plain changes to
-# standard time, so let's do that here too.  This does not change UTC
-# offsets, only tm_isdst and the time zone abbreviations.  One minor
-# plus is that this silences a zic complaint that there's no POSIX TZ
-# setting for timestamps past 2038.

-# Brazil
-
-# From Paul Eggert (1993-11-18):
-# The mayor of Rio recently attempted to change the time zone rules
-# just in his city, in order to leave more summer time for the tourist trade.
-# The rule change lasted only part of the day;
-# the federal government refused to follow the city's rules, and business
-# was in a chaos, so the mayor backed down that afternoon.
-
-# From IATA SSIM (1996-02):
-# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
-# Santa Catarina (SC), Paraná (PR), São Paulo (SP), Rio de Janeiro (RJ),
-# Espírito Santo (ES), Minas Gerais (MG), Bahia (BA), Goiás (GO),
-# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
-# [The last three states are new to this issue of the IATA SSIM.]
-
-# From Gwillim Law (1996-10-07):
-# Geography, history (Tocantins was part of Goiás until 1989), and other
-# sources of time zone information lead me to believe that AL, SE, and TO were
-# always in BR1, and so the only change was whether or not they observed DST....
-# The earliest issue of the SSIM I have is 2/91.  Each issue from then until
-# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
-# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
-# (UTC-4)....  The other two time zones given for Brazil are BR3, which is
-# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
-# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
-# become part of the state of Pernambuco).  The boundary between BR1 and BR2
-# has never been clearly stated.  They've simply been called East and West.
-# However, some conclusions can be drawn from another IATA manual: the Airline
-# Coding Directory, which lists close to 400 airports in Brazil.  For each
-# airport it gives a time zone which is coded to the SSIM.  From that
-# information, I'm led to conclude that the states of Amapá (AP), Ceará (CE),
-# Maranhão (MA), Paraíba (PR), Pernambuco (PE), Piauí (PI), and Rio Grande do
-# Norte (RN), and the eastern part of Pará (PA) are all in BR1 without DST.
-
-# From Marcos Tadeu (1998-09-27):
-# Brazilian official page 
-
-# From Jesper Nørgaard (2000-11-03):
-# [For an official list of which regions in Brazil use which time zones, see:]
-# http://pcdsh01.on.br/Fusbr.htm
-# http://pcdsh01.on.br/Fusbrhv.htm
-
-# From Celso Doria via David Madeo (2002-10-09):
-# The reason for the delay this year has to do with elections in Brazil.
-#
-# Unlike in the United States, elections in Brazil are 100% computerized and
-# the results are known almost immediately.  Yesterday, it was the first
-# round of the elections when 115 million Brazilians voted for President,
-# Governor, Senators, Federal Deputies, and State Deputies.  Nobody is
-# counting (or re-counting) votes anymore and we know there will be a second
-# round for the Presidency and also for some Governors.  The 2nd round will
-# take place on October 27th.
-#
-# The reason why the DST will only begin November 3rd is that the thousands
-# of electoral machines used cannot have their time changed, and since the
-# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
-# the Government decided to postpone DST, instead of changing the Constitution
-# (maybe, for the next elections, it will be possible to change the clock)...
-
-# From Rodrigo Severo (2004-10-04):
-# It's just the biannual change made necessary by the much hyped, supposedly
-# modern Brazilian eletronic voting machines which, apparently, can't deal
-# with a time change between the first and the second rounds of the elections.
-
-# From Steffen Thorsen (2007-09-20):
-# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:
-# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975
-
-# From Paul Schulze (2008-06-24):
-# ...by law number 11.662 of April 24, 2008 (published in the "Diario
-# Oficial da União"...) in Brazil there are changes in the timezones,
-# effective today (00:00am at June 24, 2008) as follows:
-#
-# a) The timezone UTC+5 is extinguished, with all the Acre state and the
-# part of the Amazonas state that had this timezone now being put to the
-# timezone UTC+4
-# b) The whole Pará state now is put at timezone UTC+3, instead of just
-# part of it, as was before.
-#
-# This change follows a proposal of senator Tiao Viana of Acre state, that
-# proposed it due to concerns about open television channels displaying
-# programs inappropriate to youths in the states that had the timezone
-# UTC+5 too early in the night. In the occasion, some more corrections
-# were proposed, trying to unify the timezones of any given state. This
-# change modifies timezone rules defined in decree 2.784 of 18 June,
-# 1913.
-
-# From Rodrigo Severo (2008-06-24):
-# Just correcting the URL:
-# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008
-#
-# As a result of the above Decree I believe the America/Rio_Branco
-# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
-# be created to represent the...west side of the Pará State. I
-# suggest this new timezone be called Santarem as the most
-# important/populated city in the affected area.
-#
-# This new timezone would be the same as the Rio_Branco timezone up to
-# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.
-
-# From Alex Krivenyshev (2008-06-24):
-# This is a quick reference page for New and Old Brazil Time Zones map.
-# http://www.worldtimezone.com/brazil-time-new-old.php
-#
-# - 4 time zones replaced by 3 time zones - eliminating time zone UTC-05
-# (state Acre and the part of the Amazonas will be UTC/GMT-04) - western
-# part of Par state is moving to one timezone UTC-03 (from UTC-04).
-
-# From Paul Eggert (2002-10-10):
-# The official decrees referenced below are mostly taken from
-# Decretos sobre o Horário de Verão no Brasil.
-# http://pcdsh01.on.br/DecHV.html
-
-# From Steffen Thorsen (2008-08-29):
-# As announced by the government and many newspapers in Brazil late
-# yesterday, Brazil will start DST on 2008-10-19 (need to change rule) and
-# it will end on 2009-02-15 (current rule for Brazil is fine). Based on
-# past years experience with the elections, there was a good chance that
-# the start was postponed to November, but it did not happen this year.

-# Chile
-
-# From Paul Eggert (2015-04-03):
-# Shanks & Pottenger says America/Santiago introduced standard time in
-# 1890 and rounds its UT offset to 70W40; guess that in practice this
-# was the same offset as in 1916-1919.  It also says Pacific/Easter
-# standardized on 109W22 in 1890; assume this didn't change the clocks.
-#
-# Dates for America/Santiago from 1910 to 2004 are primarily from
-# the following source, cited by Oscar van Vlijmen (2006-10-08):
-# [1] Chile Law
-# http://www.webexhibits.org/daylightsaving/chile.html
-# This contains a copy of this official table:
-# Cambios en la hora oficial de Chile desde 1900 (retrieved 2008-03-30)
-# https://web.archive.org/web/20080330200901/http://www.horaoficial.cl/cambio.htm
-# [1] needs several corrections, though.
-#
-# The first set of corrections is from:
-# [2] History of the Official Time of Chile
-# http://www.horaoficial.cl/ing/horaof_ing.html (retrieved 2012-03-06).  See:
-# https://web.archive.org/web/20120306042032/http://www.horaoficial.cl/ing/horaof_ing.html

-# https://web.archive.org/web/20121024234627/http://www.horaoficial.cl/horaof.htm
-# A fancier Spanish version (requiring mouse-clicking) is at:
-# http://www.horaoficial.cl/historia_hora.html
-# Conflicts between [1] and [2] were resolved as follows:
-#
-#  - [1] says the 1910 transition was Jan 1, [2] says Jan 10 and cites
-#    Boletín No. 1, Aviso No. 1 (1910).  Go with [2].
-#
-#  - [1] says SMT was -4:42:45, [2] says Chile's official time from
-#    1916 to 1919 was -4:42:46.3, the meridian of Chile's National
-#    Astronomical Observatory (OAN), then located in what is now
-#    Quinta Normal in Santiago.  Go with [2], rounding it to -4:42:46.
-#
-#  - [1] says the 1918 transition was Sep 1, [2] says Sep 10 and cites
-#    Boletín No. 22, Aviso No. 129/1918 (1918-08-23).  Go with [2].
-#
-#  - [1] does not give times for transitions; assume they occur
-#    at midnight mainland time, the current common practice.  However,
-#    go with [2]'s specification of 23:00 for the 1947-05-21 transition.
-#
-# Another correction to [1] is from Jesper Nørgaard Welen, who
-# wrote (2006-10-08), "I think that there are some obvious mistakes in
-# the suggested link from Oscar van Vlijmen,... for instance entry 66
-# says that GMT-4 ended 1990-09-12 while entry 67 only begins GMT-3 at
-# 1990-09-15 (they should have been 1990-09-15 and 1990-09-16
-# respectively), but anyhow it clears up some doubts too."
-#
-# Data for Pacific/Easter from 1910 through 1967 come from Shanks &
-# Pottenger.  After that, for lack of better info assume
-# Pacific/Easter is always two hours behind America/Santiago;
-# this is known to work for DST transitions starting in 2008 and
-# may well be true for earlier transitions.
-
-# From Eduardo Krell (1995-10-19):
-# The law says to switch to DST at midnight [24:00] on the second SATURDAY
-# of October....  The law is the same for March and October.
-# (1998-09-29):
-# Because of the drought this year, the government decided to go into
-# DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...
-# (unless there's another dry season next year, I guess).
-
-# From Julio I. Pacheco Troncoso (1999-03-18):
-# Because of the same drought, the government decided to end DST later,
-# on April 3, (one-time change).
-
-# From Germán Poo-Caamaño (2008-03-03):
-# Due to drought, Chile extends Daylight Time in three weeks.  This
-# is one-time change (Saturday 3/29 at 24:00 for America/Santiago
-# and Saturday 3/29 at 22:00 for Pacific/Easter)

-# 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
-# of the same day.
-# b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
-# at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
-# 01:00 on September 2.
-
-# From Steffen Thorsen (2013-02-15):
-# According to several news sources, Chile has extended DST this year,
-# they will end DST later and start DST earlier than planned.  They

-# DST End: last Saturday of April 2014 (Sun 27 Apr 2014 03:00 UTC)

-# http://www.diariooficial.interior.gob.cl/media/2015/03/03/1-large.jpg
-#
-# From Paul Eggert (2015-03-03):

-
-# From Juan Correa (2016-03-18):
-# The decree regarding DST has been published in today's Official Gazette:
-# http://www.diariooficial.interior.gob.cl/versiones-anteriores/do/20160318/
-# http://www.leychile.cl/Navegar?idNorma=1088502
-# It does consider the second Saturday of May and August as the dates
-# for the transition; and it lists DST dates until 2019, but I think
-# this scheme will stick.
-#
-# From Paul Eggert (2016-03-18):
-# For now, assume the pattern holds for the indefinite future.
-# The decree says transitions occur at 24:00; in practice this appears
-# to mean 24:00 mainland time, not 24:00 local time, so that Easter
-# Island is always two hours behind the mainland.
-

-# From Paul Eggert (2017-01-19):
-# The above says the Magallanes change expires 2019-05-11 at 24:00,
-# so in theory, they will revert to -04/-03 after that, which means
-# they will switch from -03 to -04 one hour after Santiago does that day.
-# For now, assume that they will not revert.
-
-# From Juan Correa (2018-08-13):
-# As of moments ago, the Ministry of Energy in Chile has announced the new
-# schema for DST. ...  Announcement in video (in Spanish):
-# https://twitter.com/MinEnergia/status/1029000399129374720
-# From Yonathan Dossow (2018-08-13):
-# The video says "first Saturday of September", we all know it means Sunday at
-# midnight.
-# From Tim Parenti (2018-08-13):
-# Translating the captions on the video at 0:44-0:55, "We want to announce as
-# Government that from 2019, Winter Time will be increased to 5 months, between
-# the first Saturday of April and the first Saturday of September."
-# At 2:08-2:20, "The Magallanes region will maintain its current time, as
-# decided by the citizens during 2017, but our Government will promote a
-# regional dialogue table to gather their opinion on this matter."
-# https://twitter.com/MinEnergia/status/1029009354001973248
-# "We will keep the new time policy unchanged for at least the next 4 years."
-# So we extend the new rules on Saturdays at 24:00 mainland time indefinitely.

-# ... the clocks revert back to Local Mean Time at 2 am on Sunday 15

-# Sunday 1 September.
-
-# From Rives McDow (2001-02-13):
-#
-# I have communicated several times with people there, and the last
-# time I had communications that was helpful was in 1998.  Here is
-# what was said then:
-#
-# "The general rule was that Stanley used daylight saving and the Camp
-# did not. However for various reasons many people in the Camp have
-# started to use daylight saving (known locally as 'Stanley Time')
-# There is no rule as to who uses daylight saving - it is a matter of
-# personal choice and so it is impossible to draw a map showing who
-# uses it and who does not. Any list would be out of date as soon as
-# it was produced. This year daylight saving ended on April 18/19th
-# and started again on September 12/13th.  I do not know what the rule
-# is, but can find out if you like.  We do not change at the same time
-# as UK or Chile."
-#
-# I did have in my notes that the rule was "Second Saturday in Sep at
-# 0:00 until third Saturday in Apr at 0:00".  I think that this does
-# not agree in some cases with Shanks; is this true?
-#
-# Also, there is no mention in the list that some areas in the
-# Falklands do not use DST.  I have found in my communications there
-# that these areas are on the western half of East Falkland and all of
-# West Falkland.  Stanley is the only place that consistently observes
-# DST.  Again, as in other places in the world, the farmers don't like
-# it.  West Falkland is almost entirely sheep farmers.
-#
-# I know one lady there that keeps a list of which farm keeps DST and
-# which doesn't each year.  She runs a shop in Stanley, and says that
-# the list changes each year.  She uses it to communicate to her
-# customers, catching them when they are home for lunch or dinner.
-
-# From Paul Eggert (2001-03-05):
-# For now, we'll just record the time in Stanley, since we have no
-# better info.
-
-# From Steffen Thorsen (2011-04-01):
-# The Falkland Islands will not turn back clocks this winter, but stay on
-# daylight saving time.
-#
-# One source:
-# http://www.falklandnews.com/public/story.cfm?get=5914&source=3
-#
-# We have gotten this confirmed by a clerk of the legislative assembly:
-# Normally the clocks revert to Local Mean Time (UTC/GMT -4 hours) on the
-# third Sunday of April at 0200hrs and advance to Summer Time (UTC/GMT -3
-# hours) on the first Sunday of September at 0200hrs.
-#
-# IMPORTANT NOTE: During 2011, on a trial basis, the Falkland Islands
-# will not revert to local mean time, but clocks will remain on Summer
-# time (UTC/GMT - 3 hours) throughout the whole of 2011.  Any long term
-# change to local time following the trial period will be notified.
-#
-# From Andrew Newman (2012-02-24)
-# A letter from Justin McPhee, Chief Executive,
-# Cable & Wireless Falkland Islands (dated 2012-02-22)
-# states...
-#   The current Atlantic/Stanley entry under South America expects the
-#   clocks to go back to standard Falklands Time (FKT) on the 15th April.
-#   The database entry states that in 2011 Stanley was staying on fixed
-#   summer time on a trial basis only.  FIG need to contact IANA and/or
-#   the maintainers of the database to inform them we're adopting
-#   the same policy this year and suggest recommendations for future years.
-#
-# For now we will assume permanent -03 for the Falklands
-# until advised differently (to apply for 2012 and beyond, after the 2011
-# experiment was apparently successful.)

-# Page 36 of Almanaque 2018, published by the Oceanography, Hydrography, and
-# Meteorology Service of the Uruguayan Navy, seems to give many transitions
-# with greater clarity than we've had before.  It directly references many laws
-# and decrees which are, in turn, referenced below.  They can be viewed in the
-# public archives of the Diario Oficial (in Spanish) at
-# http://www.impo.com.uy/diariooficial/
-#
-# Ley No. 3920 of 1908-06-10 placed the determination of legal time under the
-# auspices of the National Institute for the Prediction of Time.  It is unclear
-# exactly what offset was used during this period, though Ley No. 7200 of
-# 1920-04-23 used the Observatory of the National Meteorological Institute in
-# Montevideo (34° 54' 33" S, 56° 12' 45" W) as its reference meridian,
-# retarding legal time by 15 minutes 9 seconds from 1920-04-30 24:00,
-# resulting in UT-04.  Assume the corresponding LMT of UT-03:44:51 (given on
-# page 725 of the Proceedings of the Second Pan-American Scientific Congress,
-# 1915-1916) was in use, and merely became official from 1908-06-10.
-# https://www.impo.com.uy/diariooficial/1908/06/18/12
-# https://www.impo.com.uy/diariooficial/1920/04/27/9
-#
-# Ley No. 7594 of 1923-06-28 specified legal time as Observatory time advanced
-# by 44 minutes 51 seconds (UT-03) "from 30 September to 31 March", and by 14
-# minutes 51 seconds (UT-03:30) "the rest of the year"; a message from the
-# National Council of Administration the same day, published directly below the
-# law in the Diario Oficial, specified the first transition to be 1923-09-30
-# 24:00.  This effectively established standard time at UT-03:30 with 30
-# minutes DST.  Assume transitions at 24:00 on the specified days until Ley No.
-# 7919 of 1926-03-05 ended this arrangement, repealing all "laws and other
-# provisions which oppose" it, resulting in year-round UT-03:30; a Resolución
-# of 1926-03-11 puts the final transition at 1926-03-31 24:00, the same as it
-# would have been under the previous law.

-#
-# It appears Ley No. 9122 of 1933 was never published as such in the Diario
-# Oficial, but instead appeared as Document 26 in the Diario on Friday
-# 1933-10-27 as a decree made Monday 1933-10-23 and filed under the Ministry of
-# National Defense.  It reinstituted a DST of 30 minutes (to UT-03) "from the
-# last Sunday of October...until the last Saturday of March."  In accordance
-# with this provision, the first transition was explicitly specified in Article
-# 2 of the decree as Saturday 1933-10-28 at 24:00; that is, Sunday 1933-10-29
-# at 00:00.  Assume transitions at 00:00 Sunday throughout.
-#
-# Departing from the matter-of-fact nature of previous timekeeping laws, the
-# 1933 decree "consider[s] the advantages of...the advance of legal time":
-#
-#   "Whereas: The measure adopted by almost all nations at the time of the last
-#    World War still persists in North America and Europe, precisely because of
-#    the economic, hygienic, and social advantages derived from such an
-#    emergency measure...
-#
-#    Whereas: The advance of the legal time during the summer seasons, by
-#    displacing social activity near sunrise, favors the citizen populations
-#    and especially the society that creates and works..."
-#
-# It further specified that "necessary measures" be taken to ensure that
-# "public spectacles finish, in general, before [01:00]."

-# From Tim Parenti (2018-02-15):
-# Most of the Rules below, and their contemporaneous Zone lines, have been
-# updated simply to match the Almanaque 2018.  Although the document does not
-# list exact transition times, midnight transitions were already present in our
-# data here for all transitions through 2004-09, and this is both consistent
-# with prior transitions and verified in several decrees marked below between
-# 1939-09 and 2004-09, wherein the relevant text was typically of the form:
-#
-#   "From 0 hours on [date], the legal time of the entire Republic will be...
-#
-#    In accordance with [the preceding], on [previous date] at 24 hours, all
-#    clocks throughout the Republic will be [advanced/retarded] by..."
-#
-# It is possible that there is greater specificity to be found for the Rules
-# below, but it is buried in no fewer than 40 different decrees individually
-# referenced by the Almanaque for the period from 1939-09 to 2014-09.

-# From Paul Eggert (2018-06-27):

-# zone1970.tab's comments), but with the following additional restrictions:
-#
-# 1.  This file contains only ASCII characters.
-# 2.  The first data column contains exactly one country code.
-#
-# Because of (2), each row stands for an area that is the intersection
-# of a region identified by a country code and of a timezone where civil
-# clocks have agreed since 1970; this is a narrower definition than
-# that of zone1970.tab.
-#
-# This table is intended as an aid for users, to help them select timezones
-# appropriate for their practical needs.  It is not intended to take or
-# endorse any position on legal or territorial claims.
