-
-# From Paul Eggert (1999-03-31):
-# Howse writes (pp 121-125) that time zones were invented by
-# Professor Charles Ferdinand Dowd (1825-1904),
-# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
-# His pamphlet "A System of National Time for Railroads" (1870)
-# was the result of his proposals at the Convention of Railroad Trunk Lines
-# in New York City (1869-10).  His 1870 proposal was based on Washington, DC,
-# but in 1872-05 he moved the proposed origin to Greenwich.
-# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
-# and the most of the country soon followed suit.
-
-# From Paul Eggert (2005-04-16):
-# That 1883 transition occurred at 12:00 new time, not at 12:00 old time.
-# See p 46 of David Prerau, Seize the daylight, Thunder's Mouth Press (2005).
-
-# From Paul Eggert (2006-03-22):
-# A good source for time zone historical data in the US is
-# Thomas G. Shanks, The American Atlas (5th edition),
-# San Diego: ACS Publications, Inc. (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's 
-# Ten years of daylight saving from the Pittsburgh standpoint
-# (Carnegie Library of Pittsburgh, 1927).
-#
-# 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
-# :
-# "When the time is announced over the radio now, it is 'Eastern Peace
-# Time' instead of the old familiar 'Eastern War Time.'  Peace is wonderful."
-#  (August 1945) by way of confirmation.
-
-# From Joseph Gallant citing
-# George H. 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.  So even though the "US" rules have changed
-# in the latest release, other countries won't be affected.

-# Alaska
-# AK%sT is the modern abbreviation for -9:00 per USNO.
-#
-# From Paul Eggert (2001-05-30):
-# Howse writes that Alaska switched from the Julian to the Gregorian calendar,
-# and from east-of-GMT to west-of-GMT days, when the US bought it from Russia.
-# This was on 1867-10-18, a Friday; the previous day was 1867-10-06 Julian,
-# also a Friday.  Include only the time zone part of this transition,
-# ignoring the switch from Julian to Gregorian, since we can't represent
-# the Julian calendar.
-#
-# As far as we know, none of the exact locations mentioned below were
-# permanently inhabited in 1867 by anyone using either calendar.
-# (Yakutat was colonized by the Russians in 1799, but the settlement

-# From Arthur David Olson (2011-02-01):
-# Here's database-relevant material from the 2001 "Alaska History" article:
-#
-# On September 20 [1979]...DOT...officials decreed that on April 27,
-# 1980, Juneau and other nearby communities would move to Yukon Time.
-# Sitka, Petersburg, Wrangell, and Ketchikan, however, would remain on
-# Pacific Time.
-#
-# ...on September 22, 1980, DOT Secretary Neil E. Goldschmidt rescinded the
-# Department's September 1979 decision. Juneau and other communities in
-# northern Southeast reverted to Pacific Time on October 26.
-#
-# On October 28 [1983]...the Metlakatla Indian Community Council voted
-# unanimously to keep the reservation on Pacific Time.
-#
-# According to DOT official Joanne Petrie, Indian reservations are not
-# bound to follow time zones imposed by neighboring jurisdictions.
-#
-# (The last is consistent with how the database now handles the Navajo
-# Nation.)
-
-# From Arthur David Olson (2011-02-09):
-# I just spoke by phone with a staff member at the Metlakatla Indian
-# Community office (using contact information available at
-# 
-# http://www.commerce.state.ak.us/dca/commdb/CIS.cfm?Comm_Boro_name=Metlakatla
-# ).
-# It's shortly after 1:00 here on the east coast of the United States;
-# the staffer said it was shortly after 10:00 there. When I asked whether
-# that meant they were on Pacific time, they said no--they were on their
-# own time. I asked about daylight saving; they said it wasn't used. I
-# did not inquire about practices in the past.
-
-# From Arthur David Olson (2011-08-17):
-# For lack of better information, assume that Metlakatla's
-# abandonment of use of daylight saving resulted from the 1983 vote.

-#  Minutes of the Unalaska City Council Meeting, January 10, 1967:

-# 
-# and indicates that standard time was adopted effective noon, January
-# 13, 1896 (page 218), that in "1933, the Legislature decreed daylight
-# saving for the period between the last Sunday of each April and the
-# last Sunday of each September, but less than a month later repealed the

-# and Act 163 (approved 21 May 1933)."
-

-# 90...At 2 o'clock ante meridian of the last Sunday in April of each

-# Between 1944-01-01 and 1944-04-01 the State of Arizona used standard

-# Shanks partitioned Indiana into 345 regions, each with its own time history,

-# Those Hoosiers!  Such a flighty and changeable people!

-# Wayne County, Kentucky
-#
-# From
-# 
-# Lake Cumberland LIFE
-#  (1999-01-29) via WKYM-101.7:
-# Clinton County has joined Wayne County in asking the DoT to change from
-# the Central to the Eastern time zone....  The Wayne County government made
-# the same request in December.  And while Russell County officials have not
-# taken action, the majority of respondents to a poll conducted there in
-# August indicated they would like to change to "fast time" also.
-# The three Lake Cumberland counties are the farthest east of any U.S.
-# location in the Central time zone.
-#
-# From Rich Wales (2000-08-29):
-# After prolonged debate, and despite continuing deep differences of opinion,
-# Wayne County (central Kentucky) is switching from Central (-0600) to Eastern
-# (-0500) time.  They won't "fall back" this year.  See Sara Shipley,
-# The difference an hour makes, Nando Times (2000-08-29 15:33 -0400).
-#
-# From Paul Eggert (2001-07-16):
-# The final rule was published in the
-# 
-# Federal Register 65, 160 (2000-08-17), page 50154-50158.

-# so omit that change for now.
-# See America/Indiana/Knox for the Starke County, IN change.
-# See America/North_Dakota/Center for the Oliver County, ND change.

-# 
-# Federal Register 64, 203 (1999-10-21), page 56705-56707.

-# However, the Federal Register says that West Wendover already operated

-# hence a separate tz entry is not needed.

-# Michigan
-#
-# From Bob Devine (1988-01-28):
-# Michigan didn't observe DST from 1968 to 1973.
-#
-# From Paul Eggert (1999-03-31):
-# Shanks writes that Michigan started using standard time on 1885-09-18,
-# but Howse writes (pp 124-125, referring to Popular Astronomy, 1901-01)
-# that Detroit kept
-#
-#	local time until 1900 when the City Council decreed that clocks should
-#	be put back twenty-eight minutes to Central Standard Time.  Half the
-#	city obeyed, half refused.  After considerable debate, the decision
-#	was rescinded and the city reverted to Sun time.  A derisive offer to
-#	erect a sundial in front of the city hall was referred to the
-#	Committee on Sewers.  Then, in 1905, Central time was adopted
-#	by city vote.
-#
-# This story is too entertaining to be false, so go with Howse over Shanks.
-#
-# From Paul Eggert (2001-03-06):
-# Garland (1927) writes "Cleveland and Detroit advanced their clocks
-# one hour in 1914."  This change is not in Shanks.  We have no more
-# info, so omit this for now.

-# Quebec
-
-# From Paul Eggert (2013-08-30):
-# Since 1970 most of Quebec has been like Toronto.
-# However, because earlier versions of the tz database mistakenly relied on data
-# from Shanks & Pottenger saying that Quebec differed from Ontario after 1970,
-# a separate entry was created for most of Quebec.  We're loath to lose
-# its pre-1970 info, even though the tz database is normally limited to
-# zones that differ after 1970, so keep this otherwise out-of-scope entry.
-
-# Matthews and Vincent (1998) also write that Quebec east of the -63
-# meridian is supposed to observe AST, but residents as far east as
-# Natashquan use EST/EDT, and residents east of Natashquan use AST.
-# The Quebec department of justice writes in
-# "The situation in Minganie and Basse-Cote-Nord"
-# http://www.justice.gouv.qc.ca/english/publications/generale/temps-minganie-a.htm
-# that the coastal strip from just east of Natashquan to Blanc-Sablon
-# observes Atlantic standard time all year round.
-# http://www.assnat.qc.ca/Media/Process.aspx?MediaId=ANQ.Vigie.Bll.DocumentGenerique_8845en
-# says this common practice was codified into law as of 2007.
-# For lack of better info, guess this practice began around 1970, contra to

-# Ontario
-
-# From Paul Eggert (2006-07-09):
-# Shanks & Pottenger write that since 1970 most of Ontario has been like
-# Toronto.
-# Thunder Bay skipped DST in 1973.
-# Many smaller locales did not observe peacetime DST until 1974;
-# Nipigon (EST) and Rainy River (CST) are the largest that we know of.
-# Far west Ontario is like Winnipeg; far east Quebec is like Halifax.
-
-# From Mark Brader (2003-07-26):
-# [According to the Toronto Star] Orillia, Ontario, adopted DST
-# effective Saturday, 1912-06-22, 22:00; the article mentions that
-# Port Arthur (now part of Thunder Bay, Ontario) as well as Moose Jaw
-# have already done so.  In Orillia DST was to run until Saturday,
-# 1912-08-31 (no time mentioned), but it was met with considerable
-# hostility from certain segments of the public, and was revoked after
-# only two weeks -- I copied it as Saturday, 1912-07-07, 22:00, but
-# presumably that should be -07-06.  (1912-06-19, -07-12; also letters
-# earlier in June).
-#
-# Kenora, Ontario, was to abandon DST on 1914-06-01 (-05-21).
-
-# From Paul Eggert (1997-10-17):
-# Mark Brader writes that an article in the 1997-10-14 Toronto Star
-# says that Atikokan, Ontario currently does not observe DST,
-# but will vote on 11-10 whether to use EST/EDT.
-# He also writes that the
-# 
-# Ontario Time Act (1990, Chapter T.9)
-# 
-# says that Ontario east of 90W uses EST/EDT, and west of 90W uses CST/CDT.
-# Officially Atikokan is therefore on CST/CDT, and most likely this report
-# concerns a non-official time observed as a matter of local practice.
-#
-# From Paul Eggert (2000-10-02):
-# Matthews and Vincent (1998) write that Atikokan, Pickle Lake, and
-# New Osnaburgh observe CST all year, that Big Trout Lake observes
-# CST/CDT, and that Upsala and Shebandowan observe EST/EDT, all in
-# violation of the official Ontario rules.
-#
-# From Paul Eggert (2006-07-09):
-# Chris Walton (2006-07-06) mentioned an article by Stephanie MacLellan in the
-# 2005-07-21 Chronicle-Journal, which said:
-#
-#	The clocks in Atikokan stay set on standard time year-round.
-#	This means they spend about half the time on central time and
-#	the other half on eastern time.
-#
-#	For the most part, the system works, Mayor Dennis Brown said.
-#
-#	"The majority of businesses in Atikokan deal more with Eastern
-#	Canada, but there are some that deal with Western Canada," he
-#	said.  "I don't see any changes happening here."
-#
-# Walton also writes "Supposedly Pickle Lake and Mishkeegogamang
-# [New Osnaburgh] follow the same practice."
-
-# From Garry McKinnon (2006-07-14) via Chris Walton:
-# I chatted with a member of my board who has an outstanding memory
-# and a long history in Atikokan (and in the telecom industry) and he
-# can say for certain that Atikokan has been practicing the current
-# time keeping since 1952, at least.
-
-# From Paul Eggert (2006-07-17):
-# Shanks & Pottenger say that Atikokan has agreed with Rainy River
-# ever since standard time was introduced, but the information from
-# McKinnon sounds more authoritative.  For now, assume that Atikokan
-# switched to EST immediately after WWII era daylight saving time
-# ended.  This matches the old (less-populous) America/Coral_Harbour
-# entry since our cutoff date of 1970, so we can move
-# America/Coral_Harbour to the 'backward' file.

-# # Many smaller locales did not observe peacetime DST until 1974;
-# # Nipigon (EST) and Rainy River (CST) are the largest that we know of.
-#
-# In the (Toronto) Globe and Mail for Saturday, 1955-09-24, in the bottom
-# right corner of page 1, it says that Toronto will return to standard
-# time at 2 am Sunday morning (which agrees with the database), and that:
-#
-#     The one-hour setback will go into effect throughout most of Ontario,
-#     except in areas like Windsor which remains on standard time all year.
-#
-# Windsor is, of course, a lot larger than Nipigon.
-#
-# I only came across this incidentally.  I don't know if Windsor began
-# observing DST when Detroit did, or in 1974, or on some other date.
-#
-# By the way, the article continues by noting that:
-#
-#     Some cities in the United States have pushed the deadline back
-#     three weeks and will change over from daylight saving in October.

-# "Standard Time and Time Zones in Canada" appeared in

-#
-#   A list of the places in Canada using daylight saving time would
-# require yearly revision. From information kindly furnished by
-# the provincial governments and by the postmasters in many cities
-# and towns, it is found that the following places used daylight sav-
-# ing in 1930. The information for the province of Quebec is definite,
-# for the other provinces only approximate:
-#
-# 	Province	Daylight saving time used
-# Prince Edward Island	Not used.
-# Nova Scotia		In Halifax only.
-# New Brunswick		In St. John only.

-# 			St. Lambert	Cap de la Madeleine
-# 			Verdun		Loretteville
-# 			Westmount	Richmond

-# 			Longueuil	Greenfield Park
-# 			Arvida		Waterloo
-# 			Chambly-Canton	Beaulieu
-# 			Melbourne	La Tuque
-# 			St. Theophile	Buckingham
-# Ontario		Used generally in the cities and towns along

-# 			used in the northwesterlhy part.
-# Manitoba		Not used.
-# Saskatchewan		In Regina only.
-# Alberta		Not used.
-# British Columbia	Not used.
-#
-#   With some exceptions, the use of daylight saving may be said to be limited

-# Manitoba
-
-# From Rob Douglas (2006-04-06):
-# the old Manitoba Time Act - as amended by Bill 2, assented to
-# March 27, 1987 ... said ...
-# "between two o'clock Central Standard Time in the morning of
-# the first Sunday of April of each year and two o'clock Central
-# Standard Time in the morning of the last Sunday of October next
-# following, one hour in advance of Central Standard Time."...
-# I believe that the English legislation [of the old time act] had =
-# been assented to (March 22, 1967)....
-# Also, as far as I can tell, there was no order-in-council varying
-# the time of Daylight Saving Time for 2005 and so the provisions of
-# the 1987 version would apply - the changeover was at 2:00 Central
-# Standard Time (i.e. not until 3:00 Central Daylight Time).
-
-# From Paul Eggert (2006-04-10):
-# Shanks & Pottenger say Manitoba switched at 02:00 (not 02:00s)
-# starting 1966.  Since 02:00s is clearly correct for 1967 on, assume
-# it was also 02:00s in 1966.

-# Saskatchewan
-
-# From Mark Brader (2003-07-26):
-# The first actual adoption of DST in Canada was at the municipal
-# level.  As the [Toronto] Star put it (1912-06-07), "While people
-# elsewhere have long been talking of legislation to save daylight,
-# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
-# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
-# presumably late evening, as below), and would run until "the end of
-# the summer".  The discrepancy between municipal time and railroad
-# time was noted.
-
-# From Paul Eggert (2003-07-27):
-# Willett (1914-03) notes that DST "has been in operation ... in the
-# City of Moose Jaw, Saskatchewan, for one year."
-
-# From Paul Eggert (2006-03-22):
-# Shanks & Pottenger say that since 1970 this region has mostly been as Regina.
-# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
-# Other western towns (e.g. Lloydminster) are like Edmonton.
-# Matthews and Vincent (1998) write that Denare Beach and Creighton
-# are like Winnipeg, in violation of Saskatchewan law.
-
-# From W. Jones (1992-11-06):
-# The. . .below is based on information I got from our law library, the
-# provincial archives, and the provincial Community Services department.
-# A precise history would require digging through newspaper archives, and
-# since you didn't say what you wanted, I didn't bother.
-#
-# Saskatchewan is split by a time zone meridian (105W) and over the years
-# the boundary became pretty ragged as communities near it reevaluated
-# their affiliations in one direction or the other.  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.

-# 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.  Much of east BC is like Edmonton.
-# Matthews and Vincent (1998) write that Creston is like Dawson Creek.
-
-# It seems though that (re: Creston) is not entirely correct:
-
-# From Chris Walton (2011-12-01):
-# There are two areas within the Canadian province of British Columbia
-# that do not currently observe daylight saving:
-# a) The Creston Valley (includes the town of Creston and surrounding area)
-# b) The eastern half of the Peace River Regional District
-# (includes the cities of Dawson Creek and Fort St. John)
-
-# Earlier this year I stumbled across a detailed article about the time
-# keeping history of Creston; it was written by Tammy Hardwick who is the
-# manager of the Creston & District Museum. The article was written in May 2009.
-# 
-# http://www.ilovecreston.com/?p=articles&t=spec&ar=260
-# 
-# According to the article, Creston has not changed its clocks since June 1918.
-# i.e. Creston has been stuck on UTC-7 for 93 years.
-# Dawson Creek, on the other hand, changed its clocks as recently as April 1972.
-
-# Unfortunately the exact date for the time change in June 1918 remains
-# unknown and will be difficult to ascertain.  I e-mailed Tammy a few months
-# ago to ask if Sunday June 2 was a reasonable guess.  She said it was just
-# as plausible as any other date (in June).  She also said that after writing the
-# article she had discovered another time change in 1916; this is the subject
-# of another article which she wrote in October 2010.
-# 
-# http://www.creston.museum.bc.ca/index.php?module=comments&uop=view_comment&cm+id=56
-# 
-
-# Here is a summary of the three clock change events in Creston's history:
-# 1. 1884 or 1885: adoption of Mountain Standard Time (GMT-7)
-# Exact date unknown
-# 2. Oct 1916: switch to Pacific Standard Time (GMT-8)
-# Exact date in October unknown;  Sunday October 1 is a reasonable guess.
-# 3. June 1918: switch to Pacific Daylight Time (GMT-7)
-# Exact date in June unknown; Sunday June 2 is a reasonable guess.
-# note#1:
-# On Oct 27/1918 when daylight saving ended in the rest of Canada,
-# Creston did not change its clocks.
-# note#2:
-# During WWII when the Federal Government legislated a mandatory clock change,
-# Creston did not oblige.
-# note#3:
-# There is no guarantee that Creston will remain on Mountain Standard Time
-# (UTC-7) forever.
-# The subject was debated at least once this year by the town Council.
-# 
-# http://www.bclocalnews.com/kootenay_rockies/crestonvalleyadvance/news/116760809.html
-# 
-
-# During a period WWII, summer time (Daylight saying) was mandatory in Canada.
-# In Creston, that was handled by shifting the area to PST (-8:00) then applying
-# summer time to cause the offset to be -7:00, the same as it had been before
-# the change.  It can be argued that the timezone abbreviation during this
-# period should be PDT rather than MST, but that doesn't seem important enough
-# (to anyone) to further complicate the rules.
-
-# The transition dates (and times) are guesses.

-# Northwest Territories, Nunavut, Yukon
-
-# From Paul Eggert (2006-03-22):
-# Dawson switched to PST in 1973.  Inuvik switched to MST in 1979.

-#	c. 7 defines Yukon standard time as UTC-9.  This is still valid;
-#	see Interpretation Act, R.S.C. 1985, c. I-21, s. 35(1).
-#	* C.O. 1973/214 switched Yukon to PST on 1973-10-28 00:00.
-#	* O.I.C. 1980/02 established DST.
-#	* O.I.C. 1987/056 changed DST to Apr firstSun 2:00 to Oct lastSun 2:00.
-# Shanks & Pottenger say Yukon's 1973-10-28 switch was at 2:00; go
-# with Englander.

-# Here is a link to the old daylight saving portion of the interpretation
-# act which was last updated in 1987:
-# http://www.gov.yk.ca/legislation/regs/oic1987_056.pdf
-
-# From Rives McDow (1999-09-04):
-# Nunavut ... moved ... to incorporate the whole territory into one time zone.
-# 
-# Nunavut moves to single time zone Oct. 31
-# 
-#
-# From Antoine Leca (1999-09-06):
-# We then need to create a new timezone for the Kitikmeot region of Nunavut
-# to differentiate it from the Yellowknife region.
-
-# From Paul Eggert (1999-09-20):
-# 
-# Basic Facts: The New Territory
-#  (1999) reports that Pangnirtung operates on eastern time,
-# and that Coral Harbour does not observe DST.  We don't know when
-# Pangnirtung switched to eastern time; we'll guess 1995.
-
-# From Rives McDow (1999-11-08):
-# On October 31, when the rest of Nunavut went to Central time,
-# Pangnirtung wobbled.  Here is the result of their wobble:
-#
-# The following businesses and organizations in Pangnirtung use Central Time:
-#
-#	First Air, Power Corp, Nunavut Construction, Health Center, RCMP,
-#	Eastern Arctic National Parks, A & D Specialist
-#
-# The following businesses and organizations in Pangnirtung use Eastern Time:
-#
-#	Hamlet office, All other businesses, Both schools, Airport operator
-#
-# This has made for an interesting situation there, which warranted the news.
-# No one there that I spoke with seems concerned, or has plans to
-# change the local methods of keeping time, as it evidently does not
-# really interfere with any activities or make things difficult locally.
-# They plan to celebrate New Year's turn-over twice, one hour apart,
-# so it appears that the situation will last at least that long.
-# The Nunavut Intergovernmental Affairs hopes that they will "come to
-# their senses", but the locals evidently don't see any problem with
-# the current state of affairs.
-
-# From Michaela Rodrigue, writing in the
-# 
-# Nunatsiaq News (1999-11-19):
-# Clyde River, Pangnirtung and Sanikiluaq now operate with two time zones,
-# central - or Nunavut time - for government offices, and eastern time
-# for municipal offices and schools....  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.  Baffin Island, which is crossed by the
-# Central, Eastern and Atlantic Time zones only uses Eastern Time.
-# Gjoa Haven, Taloyoak and Pelly Bay all use Mountain instead of
-# Central Time and Southampton Island [in the Central zone] is not
-# required to use daylight savings.
-
-# From
-# 
-# Nunavut now has two time zones
-#  (2000-11-10):
-# The Nunavut government would allow its employees in Kugluktuk and
-# Cambridge Bay to operate on central time year-round, putting them
-# one hour behind the rest of Nunavut for six months during the winter.
-# At the end of October the two communities had rebelled against
-# Nunavut's unified time zone, refusing to shift to eastern time with
-# the rest of the territory for the winter.  Cambridge Bay remained on
-# central time, while Kugluktuk, even farther west, reverted to
-# mountain time, which they had used before the advent of Nunavut's
-# unified time zone in 1999.
-#
-# From Rives McDow (2001-01-20), quoting the Nunavut government:
-# The preceding decision came into effect at midnight, Saturday Nov 4, 2000.
-
-# From Paul Eggert (2000-12-04):
-# Let's just keep track of the official times for now.
-
-# From Rives McDow (2001-03-07):
-# The premier of Nunavut has issued a ministerial statement advising
-# that effective 2001-04-01, the territory of Nunavut will revert
-# back to three time zones (mountain, central, and eastern).  Of the
-# cities in Nunavut, Coral Harbor is the only one that I know of that
-# has said it will not observe dst, staying on EST year round.  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 maps at
-# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SWE.jpg
-# http://inms-ienm.nrc-cnrc.gc.ca/images/time_services/TZ01SSE.jpg
-# (both dated 2003), and
-# 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 (2005-07-26):
-# For lack of better information, assume that Southampton Island observed
-# daylight saving only during wartime.
-
-# 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.

-
-# From Paul Eggert (2001-03-05):
-# The Investigation and Analysis Service of the
-# Mexican Library of Congress (MLoC) has published a
-# 
-# history of Mexican local time (in Spanish)
-# .
-#
-# 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.  I think they can best be explained by supposing that
-# the researchers who prepared the Decrees page failed to find some of
-# the relevant documents.
-
-# From Alan Perry (1996-02-15):
-# A guy from our Mexico subsidiary finally found the Presidential Decree
-# outlining the timezone changes in Mexico.
-#
-# ------------- Begin Forwarded Message -------------
-#
-# I finally got my hands on the Official Presidential Decree that sets up the
-# rules for the DST changes. The rules are:
-#
-# 1. The country is divided in 3 timezones:
-#    - Baja California Norte (the Mexico/BajaNorte TZ)
-#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
-#    - The rest of the country (the Mexico/General TZ)
-#
-# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
-#    at 2:00 AM, the times in each zone are as follows:
-#    BajaNorte: GMT+7
-#    BajaSur:   GMT+6
-#    General:   GMT+5
-#
-# 3. The rest of the year, the times are as follows:
-#    BajaNorte: GMT+8
-#    BajaSur:   GMT+7
-#    General:   GMT+6
-#
-# The Decree was published in Mexico's Official Newspaper on January 4th.
-#
-# -------------- End Forwarded Message --------------
-# From Paul Eggert (1996-06-12):
-# For an English translation of the decree, see
-# 
-# "Diario Oficial: Time Zone Changeover" (1996-01-04).
-# 
-
-# From Rives McDow (1998-10-08):
-# The State of Quintana Roo has reverted back to central STD and DST times
-# (i.e. UTC -0600 and -0500 as of 1998-08-02).
-
-# From Rives McDow (2000-01-10):
-# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
-# zone 5 hours from the International Date Line, and will not observe daylight
-# savings time so as to stay on the same time zone as the southern part of
-# Arizona year round.
-
-# From Jesper Norgaard, translating
-#  (2001-01-17):
-# In Oaxaca, the 55.000 teachers from the Section 22 of the National
-# Syndicate of Education Workers, refuse to apply daylight saving each
-# year, so that the more than 10,000 schools work at normal hour the
-# whole year.
-
-# From Gwillim Law (2001-01-19):
-#  ... says
-# (translated):...
-# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced
-# that Summer Time will be reduced from seven to five months, starting
-# this year....
-# 
-# [translated], says "summer time will ... take effect on the first Sunday
-# in May, and end on the last Sunday of September.
-
-# From Arthur David Olson (2001-01-25):
-# The 2001-01-24 traditional Washington Post contained the page one
-# story "Timely Issue Divides Mexicans."...
-# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
-# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
-# Mexico City and its 20 million residents on a different time than
-# the rest of the country..." In particular, Lopez Obrador would abolish
-# observation of Daylight Saving Time.
-
-# 
-# Official statute published by the Energy Department
-#  (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
-# and Sonora with no DST.  This was reported by Jesper Norgaard (2001-02-03).
-
-# From Paul Eggert (2001-03-03):
-#
-# 
-# James F. Smith writes in today's LA Times
-# 
-# * Sonora will continue to observe standard time.
-# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
-#   the Federal District will not adopt DST.
-# * 4 of 16 district leaders announced they'll ignore the decree.
-# * The decree does not affect federal-controlled facilities including
-#   the airport, banks, hospitals, and schools.
-#
-# For now we'll assume that the Federal District will bow to federal rules.
-
-# From Jesper Norgaard (2001-04-01):
-# I found some references to the Mexican application of daylight
-# saving, which modifies what I had already sent you, stating earlier
-# that a number of northern Mexican states would go on daylight
-# saving. The modification reverts this to only cover Baja California
-# (Norte), while all other states (except Sonora, who has no daylight
-# saving all year) will follow the original decree of president
-# Vicente Fox, starting daylight saving May 6, 2001 and ending
-# September 30, 2001.
-# References: "Diario de Monterrey" 
-# Palabra  (2001-03-31)
-
-# From Reuters (2001-09-04):
-# Mexico's Supreme Court on Tuesday declared that daylight savings was
-# unconstitutional in Mexico City, creating the possibility the
-# capital will be in a different time zone from the rest of the nation
-# next year....  The Supreme Court's ruling takes effect at 2:00
-# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
-# standard time. "This is so residents of the Federal District are not
-# subject to unexpected time changes," a statement from the court said.
-
-# From Jesper Norgaard Welen (2002-03-12):
-# ... consulting my local grocery store(!) and my coworkers, they all insisted
-# that a new decision had been made to reinstate US style DST in Mexico....
-# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
-# confirms this.  Sonora as usual is the only state where DST is not applied.
-
-# From Steffen Thorsen (2009-12-28):
-#
-# Steffen Thorsen wrote:
-# > Mexico's House of Representatives has approved a proposal for northern
-# > Mexico's border cities to share the same daylight saving schedule as
-# > the United States.
-# Now this has passed both the Congress and the Senate, so starting from
-# 2010, some border regions will be the same:

-# From Paul Eggert (2006-03-22):
-# Formerly there was an America/Ensenada zone, which differed from
-# America/Tijuana only in that it did not observe DST from 1976
-# through 1995.  This was as per Shanks (1999).  But Shanks & Pottenger say
-# Ensenada did not observe DST from 1948 through 1975.  Guy Harris reports
-# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
-# Tijuana observe DST," which agrees with Shanks & Pottenger but implies that
-# DST-observance was a town-by-town matter back then.  This concerns
-# data after 1970 so most likely there should be at least one Zone
-# other than America/Tijuana for Baja, but it's not clear yet what its
-# name or contents should be.

-# I'm in Maryland which is now observing United States Eastern Daylight

-# http://media.enet.cu/radioreloj
-# , a Cuban information station, and heard
-# the time announced as "ocho cuarenta y cuatro" ("eight forty-four"),
-# indicating that Cuba is still on standard time.
-
-# From Steffen Thorsen (2008-03-12):
-# It seems that Cuba will start DST on Sunday, 2007-03-16...
-# It was announced yesterday, according to this source (in Spanish):
-# 
-# http://www.nnc.cubaweb.cu/marzo-2008/cien-1-11-3-08.htm

-#
-# Some more background information is posted here:
-# 
-# http://www.timeanddate.com/news/time/cuba-starts-dst-march-16.html
-# 
-#
-# The article also says that Cuba has been observing DST since 1963,
-# while Shanks (and tzdata) has 1965 as the first date (except in the
-# 1940's). Many other web pages in Cuba also claim that it has been
-# observed since 1963, but with the exception of 1970 - an exception
-# which is not present in tzdata/Shanks. So there is a chance we need to
-# change some historic records as well.

-# Haiti
-# From Gwillim Law (2005-04-15):
-# Risto O. Nykanen wrote me that Haiti is now on DST.
-# I searched for confirmation, and I found a
-#  press release
-# on the Web page of the Haitian Consulate in Chicago (2005-03-31),
-# .  Translated from French, it says:
-#
-#  "The Prime Minister's Communication Office notifies the public in general
-#   and the press in particular that, following a decision of the Interior
-#   Ministry and the Territorial Collectivities [I suppose that means the
-#   provinces], Haiti will move to Eastern Daylight Time in the night from next
-#   Saturday the 2nd to Sunday the 3rd.
-#
-#  "Consequently, the Prime Minister's Communication Office wishes to inform
-#   the population that the country's clocks will be set forward one hour
-#   starting at midnight.  This provision will hold until the last Saturday in
-#   October 2005.
-#
-#  "Port-au-Prince, March 31, 2005"
-#
-# From Steffen Thorsen (2006-04-04):
-# I have been informed by users that Haiti observes DST this year like
-# last year, so the current "only" rule for 2005 might be changed to a
-# "max" rule or to last until 2006. (Who knows if they will observe DST
-# next year or if they will extend their DST like US/Canada next year).
-#
-# I have found this article about it (in French):
-# http://www.haitipressnetwork.com/news.cfm?articleID=7612
-#
-# The reason seems to be an energy crisis.
-
-# From Stephen Colebourne (2007-02-22):
-# Some IATA info: Haiti won't be having DST in 2007.
-
-# From Steffen Thorsen (2012-03-11):
-# According to several news sources, Haiti will observe DST this year,
-# apparently using the same start and end date as USA/Canada.
-# So this means they have already changed their time.
-#
-# http://www.alterpresse.org/spip.php?article12510
-# http://radiovision2000haiti.net/home/?p=13253
-#
-# From Arthur David Olson (2012-03-11):
-# The alterpresse.org source seems to show a US-style leap from 2:00 a.m. to
-# 3:00 a.m. rather than the traditional Haitian jump at midnight.
-# Assume a US-style fall back as well.
-
-# From Steffen Thorsen (2013-03-10):
-# It appears that Haiti is observing DST this year as well, same rules
-# as US/Canada.  They did it last year as well, and it looks like they
-# are going to observe DST every year now...
