-# A good source for time zone historical data outside the U.S. is
-# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
-# San Diego: ACS Publications, Inc. (2003).
-#
-# For data circa 1899, a common source is:
-# Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94
-# .
-#
-# Gwillim Law writes that a good source
-# for recent time zone data is the International Air Transport
-# Association's Standard Schedules Information Manual (IATA SSIM),
-# published semiannually.  Law sent in several helpful summaries
-# of the IATA's data after 1990.
-#
-# Except where otherwise noted, Shanks & Pottenger is the source for
-# entries through 1990, and IATA SSIM is the source for entries afterwards.
-#
-# Earlier editions of these tables used the North American style (e.g. ARST and
-# ARDT for Argentine Standard and Daylight Time), but the following quote
-# suggests that it's better to use European style (e.g. ART and ARST).
-#	I suggest the use of _Summer time_ instead of the more cumbersome
-#	_daylight-saving time_.  _Summer time_ seems to be in general use
-#	in Europe and South America.
-#	-- E O Cutler, _New York Times_ (1937-02-14), quoted in
-#	H L Mencken, _The American Language: Supplement I_ (1960), p 466
-#
-# Earlier editions of these tables also used the North American style
-# for time zones in Brazil, but this was incorrect, as Brazilians say
-# "summer time".  Reinaldo Goulart, a Sao Paulo businessman active in
-# the railroad sector, writes (1999-07-06):
-#	The subject of time zones is currently a matter of discussion/debate in
-#	Brazil.  Let's say that "the Brasilia time" is considered the
-#	"official time" because Brasilia is the capital city.
-#	The other three time zones are called "Brasilia time "minus one" or
-#	"plus one" or "plus two".  As far as I know there is no such
-#	name/designation as "Eastern Time" or "Central Time".
-# So I invented the following (English-language) abbreviations for now.

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

-# From Paul Eggert (2004-05-24):

-#
-# The following eight (8) provinces pulled clocks back to UTC-04:00 at
-# midnight Monday May 31st. (that is, the night between 05/31 and 06/01).
-# Apparently, all nine provinces would go back to UTC-03:00 at the same

-#
-# Catamarca, Chubut, La Rioja, San Juan, San Luis, Santa Cruz,
-# Tierra del Fuego, Tucuman.
-#
-# From Mariano Absatz (2004-06-14):
-# ... this weekend, the Province of Tucuman decided it'd go back to UTC-03:00
-# yesterday midnight (that is, at 24:00 Saturday 12th), since the people's
-# annoyance with the change is much higher than the power savings obtained....
-#
-# 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.net/dst_news/dst_news_argentina02.html
-# 
-
-# From Jesper Norgaard 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 21.st 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 Norgaard 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 (2008-06-30):
-# Unless otherwise specified, data 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
-# 
-# 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...
-#
-# I'm enclosing a patch that does what I say... regretfully, the San Luis
-# timezone must be called "WART/WARST" even when most of the time (like,
-# right now) WARST == ART... that is, since last Sunday, all the country
-# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
-# of the country calls it "ART".
-# ...
-
-# From Alexander Krivenyshev (2010-04-09):
-# According to news reports from El Diario de la Republica 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

-# 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 (2013-09-05):
-# Perhaps San Luis operates on the legal fiction that it is at UTC-4
-# with perpetual summer time, but ordinary usage typically seems to
-# just say it's at UTC-3; see, for example,
-# .
-# 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 time stamps past 2038.
-
-# From Paul Eggert (2013-02-21):
-# Milne says Cordoba time was -4:16:48.2.  Round to the nearest second.

-
-# 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), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
-# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (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 Goias 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 Amapa (AP), Ceara (CE),
-# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
-# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.

-# Brazilian official page
-# 
-
-# From Jesper Norgaard (2000-11-03):

-# 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 Uniao"...) in Brazil there are changes in the timezones,
-# effective today (00:00am at June 24, 2008) as follows:
-#
-# a) The timezone UTC+5 is e[x]tinguished, 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 Para 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 Para 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

-
-# From Steffen Thorsen (2008-08-29):
-# As announced by the government and many newspapers in Brazil late

-# it will end on 2009-02-15 (current rule for Brazil is fine). Based on

-# Chile
-
-# 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 Oscar van Vlijmen (2006-10-08):

-
-# From Jesper Norgaard Welen (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.

-# From Paul Eggert (2006-12-27):
-# The following data for Chile and America/Santiago are from

-# Jesper Norgaard Welen.  The data for Pacific/Easter are from Shanks
-# & Pottenger, except with DST transitions after 1932 cloned from

-# but we have no other source.

-# From German Poo-Caaman~o (2008-03-03):
-# Due to drought, Chile extends Daylight Time in three weeks.  This

-# The Chilean Government has decided to postpone the entrance into winter time
-# (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
-# been yet formalized but it will within the next days.
-# Quote from the website communication:
-#
-# 6. For the year 2012, the dates of entry into winter time will be as follows:
-# a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
-# 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,

-# September.  It is anticipated that the clocks will revert back at 2

-# 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 summer time for the Falklands
-# until advised differently (to apply for 2012 and beyond, after the 2011
-# experiment was apparently successful.)
