9# From Paul Eggert (2006-03-22):
10# A good source for time zone historical data outside the U.S. is
11# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
12# San Diego: ACS Publications, Inc. (2003).
13#
14# Gwillim Law writes that a good source
15# for recent time zone data is the International Air Transport
16# Association's Standard Schedules Information Manual (IATA SSIM),
17# published semiannually.  Law sent in several helpful summaries
18# of the IATA's data after 1990.
19#
20# Except where otherwise noted, Shanks & Pottenger is the source for
21# entries through 1990, and IATA SSIM is the source for entries afterwards.
22#
23# Earlier editions of these tables used the North American style (e.g. ARST and
24# ARDT for Argentine Standard and Daylight Time), but the following quote
25# suggests that it's better to use European style (e.g. ART and ARST).
26#       I suggest the use of _Summer time_ instead of the more cumbersome
27#       _daylight-saving time_.  _Summer time_ seems to be in general use
28#       in Europe and South America.
29#       -- E O Cutler, _New York Times_ (1937-02-14), quoted in
30#       H L Mencken, _The American Language: Supplement I_ (1960), p 466
31#
32# Earlier editions of these tables also used the North American style
33# for time zones in Brazil, but this was incorrect, as Brazilians say
34# "summer time".  Reinaldo Goulart, a Sao Paulo businessman active in
35# the railroad sector, writes (1999-07-06):
36#       The subject of time zones is currently a matter of discussion/debate in
37#       Brazil.  Let's say that "the Brasilia time" is considered the
38#       "official time" because Brasilia is the capital city.
39#       The other three time zones are called "Brasilia time "minus one" or
40#       "plus one" or "plus two".  As far as I know there is no such
41#       name/designation as "Eastern Time" or "Central Time".
42# So I invented the following (English-language) abbreviations for now.
43# Corrections are welcome!

103#
104# From Rives McDow (2000-01-10):
105# On October 3, 1999, 0:00 local, Argentina implemented daylight savings time,

109# From Paul Eggert (2007-12-28):
110# DST was set to expire on March 5, not March 3, but since it was converted
111# to standard time on March 3 it's more convenient for us to pretend that
112# it ended on March 3.

114#
115# From Peter Gradelski via Steffen Thorsen (2000-03-01):
116# We just checked with our Sao Paulo office and they say the government of
117# Argentina decided not to become one of the countries that go on or off DST.
118# So Buenos Aires should be -3 hours from GMT at all times.
119#
120# From Fabian L. Arce Jofre (2000-04-04):
121# The law that claimed DST for Argentina was derogated by President Fernando
122# de la Rua on March 2, 2000, because it would make people spend more energy
123# in the winter time, rather than less.  The change took effect on March 3.
124#
125# From Mariano Absatz (2001-06-06):
126# one of the major newspapers here in Argentina said that the 1999
127# Timezone Law (which never was effectively applied) will (would?) be
128# in effect.... The article is at
129# http://ar.clarin.com/diario/2001-06-06/e-01701.htm
130# ... The Law itself is "Ley No 25155", sanctioned on 1999-08-25, enacted
131# 1999-09-17, and published 1999-09-21.  The official publication is at:

134#
135# (2001-06-12):
136# the timezone for Argentina will not change next Sunday.
137# Apparently it will do so on Sunday 24th....
138# http://ar.clarin.com/diario/2001-06-12/s-03501.htm
139#
140# (2001-06-25):
141# Last Friday (yes, the last working day before the date of the change), the
142# Senate annulled the 1999 law that introduced the changes later postponed.
143# http://www.clarin.com.ar/diario/2001-06-22/s-03601.htm
144# It remains the vote of the Deputies..., but it will be the same....
145# This kind of things had always been done this way in Argentina.
146# We are still -03:00 all year round in all of the country.
147#
148# From Steffen Thorsen (2007-12-21):
149# A user (Leonardo Chaim) reported that Argentina will adopt DST....
150# all of the country (all Zone-entries) are affected.  News reports like
151# http://www.lanacion.com.ar/opinion/nota.asp?nota_id=973037 indicate
152# that Argentina will use DST next year as well, from October to
153# March, although exact rules are not given.
154#
155# From Jesper Norgaard Welen (2007-12-26)
156# The last hurdle of Argentina DST is over, the proposal was approved in
157# the lower chamber too (Deputados) with a vote 192 for and 2 against.
158# By the way thanks to Mariano Absatz and Daniel Mario Vega for the link to
159# the original scanned proposal, where the dates and the zero hours are
160# clear and unambiguous...This is the article about final approval:

165# From Paul Eggert (2007-12-22):
166# For dates after mid-2008, the following rules are my guesses and
167# are quite possibly wrong, but are more likely than no DST at all.
168
169# From Alexander Krivenyshev (2008-09-05):
170# As per message from Carlos Alberto Fonseca Arauz (Nicaragua),
171# Argentina will start DST on Sunday October 19, 2008.

255# The following eight (8) provinces pulled clocks back to UTC-04:00 at

264# ... this weekend, the Province of Tucuman decided it'd go back to UTC-03:00
265# yesterday midnight (that is, at 24:00 Saturday 12th), since the people's
266# annoyance with the change is much higher than the power savings obtained....

268# From Gwillim Law (2004-06-14):
269# http://www.lanacion.com.ar/04/06/10/de_609078.asp ...
270#     "The time change in Tierra del Fuego was a conflicted decision from
271#   the start.  The government had decreed that the measure would take
272#   effect on June 1, but a normative error forced the new time to begin
273#   three days earlier, from a Saturday to a Sunday....
274# Our understanding was that the change was originally scheduled to take place
275# on June 1 at 00:00 in Chubut, Santa Cruz, Tierra del Fuego (and some other
276# provinces).  Sunday was May 30, only two days earlier.  So the article
277# contains a contradiction.  I would give more credence to the Saturday/Sunday
278# date than the "three days earlier" phrase, and conclude that Tierra del
279# Fuego set its clocks back at 2004-05-30 00:00.

332
333# From Jesper Norgaard Welen (2008-01-25):
334# Unfortunately the below page has become defunct, about the San Luis
335# time change. Perhaps because it now is part of a group of pages "Most
336# important pages of 2008."
337#
338# You can use
339# <a href="http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834">
340# http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
341# </a>
342# instead it seems. Or use "Buscador" from the main page of the San Luis
343# government, and fill in "huso" and click OK, and you will get 3 pages
344# from which the first one is identical to the above.
345
346# From Mariano Absatz (2008-01-28):
347# I can confirm that the Province of San Luis (and so far only that
348# province) decided to go back to UTC-3 effective midnight Jan 20th 2008
349# (that is, Monday 21st at 0:00 is the time the clocks were delayed back
350# 1 hour), and they intend to keep UTC-3 as their timezone all year round
351# (that is, unless they change their mind any minute now).
352#
353# So we'll have to add yet another city to 'southamerica' (I think San
354# Luis city is the mos populated city in the Province, so it'd be
355# America/Argentina/San_Luis... of course I can't remember if San Luis's
356# history of particular changes goes along with Mendoza or San Juan :-(
357# (I only remember not being able to collect hard facts about San Luis
358# back in 2004, when these provinces changed to UTC-4 for a few days, I
359# mailed them personally and never got an answer).
360
361# From Paul Eggert (2008-06-30):
362# Unless otherwise specified, data are from Shanks & Pottenger through 1992,
363# from the IATA otherwise.  As noted below, Shanks & Pottenger say that
364# America/Cordoba split into 6 subregions during 1991/1992, one of which
365# was America/San_Luis, but we haven't verified this yet so for now we'll
366# keep America/Cordoba a single region rather than splitting it into the
367# other 5 subregions.
368
369# From Mariano Absatz (2009-03-13):
370# Yesterday (with our usual 2-day notice) the Province of San Luis
371# decided that next Sunday instead of "staying" @utc-03:00 they will go
372# to utc-04:00 until the second Saturday in October...

389# The press release says:
390#  (...) anunció que el próximo domingo a las 00:00 los puntanos deberán
391# atrasar una hora sus relojes.
392#
393# A partir de entonces, San Luis establecerá el huso horario propio de
394# la Provincia. De esta manera, durante el periodo del calendario anual
395# 2009, el cambio horario quedará comprendido entre las 00:00 del tercer
396# domingo de marzo y las 24:00 del segundo sábado de octubre.
397# Quick&dirty translation
398# (...) announced that next Sunday, at 00:00, Puntanos (the San Luis
399# inhabitants) will have to turn back one hour their clocks
400#
401# Since then, San Luis will establish its own Province timezone. Thus,
402# during 2009, this timezone change will run from 00:00 the third Sunday
403# in March until 24:00 of the second Saturday in October.
404
405# From Mariano Absatz (2009-10-16):
406# ...the Province of San Luis is a case in itself.

408# The Law at
409# <a href="http://www.diputadossanluis.gov.ar/diputadosasp/paginas/verNorma.asp?NormaID=276>"

412# is ambiguous because establishes a calendar from the 2nd Sunday in
413# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
414# complement of that starting on the 2nd Sunday of March at 0:00 and
415# ending on the 2nd Saturday of March at 24:00.
416#
417# This clearly breaks every time the 1st of March or October is a Sunday.
418#
419# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
420# Sunday of October and March.
421#
422# The problem is that the changes in the rest of the Provinces that did
423# change in 2007/2008, were made according to the Federal Law and Decrees
424# that did so on the 3rd Sunday of October and March.
425#
426# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
427# (October 11th) at 0:00.
428#
429# So I guess a new set of rules, besides "Arg", must be made and the last
430# America/Argentina/San_Luis entries should change to use these...
431#
432# I'm enclosing a patch that does what I say... regretfully, the San Luis
433# timezone must be called "WART/WARST" even when most of the time (like,
434# right now) WARST == ART... that is, since last Sunday, all the country
435# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
436# of the country calls it "ART".

438
439# From Alexander Krivenyshev (2010-04-09):
440# According to news reports from El Diario de la Republica Province San
441# Luis, Argentina (standard time UTC-04) will keep Daylight Saving Time

454# From Mariano Absatz (2010-04-12):
455# yes...I can confirm this...and given that San Luis keeps calling
456# UTC-03:00 "summer time", we should't just let San Luis go back to "Arg"
457# rules...San Luis is still using "Western ARgentina Time" and it got
458# stuck on Summer daylight savings time even though the summer is over.

651# From Paul Eggert (1993-11-18):
652# The mayor of Rio recently attempted to change the time zone rules
653# just in his city, in order to leave more summer time for the tourist trade.
654# The rule change lasted only part of the day;
655# the federal government refused to follow the city's rules, and business
656# was in a chaos, so the mayor backed down that afternoon.
657
658# From IATA SSIM (1996-02):
659# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
660# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
661# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
662# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
663# [The last three states are new to this issue of the IATA SSIM.]
664
665# From Gwillim Law (1996-10-07):
666# Geography, history (Tocantins was part of Goias until 1989), and other
667# sources of time zone information lead me to believe that AL, SE, and TO were
668# always in BR1, and so the only change was whether or not they observed DST....
669# The earliest issue of the SSIM I have is 2/91.  Each issue from then until
670# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
671# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
672# (UTC-4)....  The other two time zones given for Brazil are BR3, which is
673# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
674# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
675# become part of the state of Pernambuco).  The boundary between BR1 and BR2
676# has never been clearly stated.  They've simply been called East and West.
677# However, some conclusions can be drawn from another IATA manual: the Airline
678# Coding Directory, which lists close to 400 airports in Brazil.  For each
679# airport it gives a time zone which is coded to the SSIM.  From that
680# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
681# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
682# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.

693
694# From Celso Doria via David Madeo (2002-10-09):
695# The reason for the delay this year has to do with elections in Brazil.
696#
697# Unlike in the United States, elections in Brazil are 100% computerized and
698# the results are known almost immediately.  Yesterday, it was the first
699# round of the elections when 115 million Brazilians voted for President,
700# Governor, Senators, Federal Deputies, and State Deputies.  Nobody is
701# counting (or re-counting) votes anymore and we know there will be a second
702# round for the Presidency and also for some Governors.  The 2nd round will
703# take place on October 27th.
704#
705# The reason why the DST will only begin November 3rd is that the thousands
706# of electoral machines used cannot have their time changed, and since the
707# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
708# the Government decided to postpone DST, instead of changing the Constitution
709# (maybe, for the next elections, it will be possible to change the clock)...
710
711# From Rodrigo Severo (2004-10-04):
712# It's just the biannual change made necessary by the much hyped, supposedly
713# modern Brazilian eletronic voting machines which, apparently, can't deal
714# with a time change between the first and the second rounds of the elections.
715
716# From Steffen Thorsen (2007-09-20):
717# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00:

720# From Paul Schulze (2008-06-24):
721# ...by law number 11.662 of April 24, 2008 (published in the "Diario
722# Oficial da Uniao"...) in Brazil there are changes in the timezones,
723# effective today (00:00am at June 24, 2008) as follows:
724#
725# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the
726# part of the Amazonas state that had this timezone now being put to the
727# timezone UTC+4
728# b) The whole Para state now is put at timezone UTC+3, instead of just
729# part of it, as was before.
730#
731# This change follows a proposal of senator Tiao Viana of Acre state, that
732# proposed it due to concerns about open television channels displaying
733# programs inappropriate to youths in the states that had the timezone
734# UTC+5 too early in the night. In the occasion, some more corrections
735# were proposed, trying to unify the timezones of any given state. This
736# change modifies timezone rules defined in decree 2.784 of 18 June,
737# 1913.
738
739# From Rodrigo Severo (2008-06-24):
740# Just correcting the URL:

743# </a>
744#
745# As a result of the above Decree I believe the America/Rio_Branco
746# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall
747# be created to represent the...west side of the Para State. I
748# suggest this new timezone be called Santarem as the most
749# important/populated city in the affected area.
750#
751# This new timezone would be the same as the Rio_Branco timezone up to
752# the 2008/06/24 change which would be to UTC-3 instead of UTC-4.

770# From Steffen Thorsen (2008-08-29):

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

1232# As stated in the website of the Chilean Energy Ministry
1233# http://www.minenergia.cl/ministerio/noticias/generales/gobierno-anuncia-fechas-de-cambio-de.html
1234# The Chilean Government has decided to postpone the entrance into winter time
1235# (to leave DST) from March 11 2012 to April 28th 2012. The decision has not
1236# been yet formalized but it will within the next days.
1237# Quote from the website communication:
1238#
1239# 6. For the year 2012, the dates of entry into winter time will be as follows:
1240# a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
1241# 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00
1242# of the same day.
1243# b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,
1244# at 23:59:59, instead of passing to 0:00, the time should be adjusted to be
1245# 01:00 on September 2.

1385# From Rives McDow (2001-02-13):
1386#
1387# I have communicated several times with people there, and the last
1388# time I had communications that was helpful was in 1998.  Here is
1389# what was said then:
1390#
1391# "The general rule was that Stanley used daylight saving and the Camp
1392# did not. However for various reasons many people in the Camp have
1393# started to use daylight saving (known locally as 'Stanley Time')
1394# There is no rule as to who uses daylight saving - it is a matter of
1395# personal choice and so it is impossible to draw a map showing who
1396# uses it and who does not. Any list would be out of date as soon as
1397# it was produced. This year daylight saving ended on April 18/19th
1398# and started again on September 12/13th.  I do not know what the rule
1399# is, but can find out if you like.  We do not change at the same time
1400# as UK or Chile."
1401#
1402# I did have in my notes that the rule was "Second Saturday in Sep at
1403# 0:00 until third Saturday in Apr at 0:00".  I think that this does
1404# not agree in some cases with Shanks; is this true?
1405#
1406# Also, there is no mention in the list that some areas in the
1407# Falklands do not use DST.  I have found in my communications there
1408# that these areas are on the western half of East Falkland and all of
1409# West Falkland.  Stanley is the only place that consistently observes
1410# DST.  Again, as in other places in the world, the farmers don't like
1411# it.  West Falkland is almost entirely sheep farmers.
1412#
1413# I know one lady there that keeps a list of which farm keeps DST and
1414# which doesn't each year.  She runs a shop in Stanley, and says that
1415# the list changes each year.  She uses it to communicate to her
1416# customers, catching them when they are home for lunch or dinner.

1446#   clocks to go back to standard Falklands Time (FKT) on the 15th April.
1447#   The database entry states that in 2011 Stanley was staying on fixed
1448#   summer time on a trial basis only.  FIG need to contact IANA and/or
1449#   the maintainers of the database to inform them we're adopting
1450#   the same policy this year and suggest recommendations for future years.
1451#
1452# For now we will assume permanent summer time for the Falklands
1453# until advised differently (to apply for 2012 and beyond, after the 2011
1454# experiment was apparently successful.)
