# This file is in the public domain, so clarified as of
|
||
# 2009-05-17 by Arthur David Olson.
|
||
|
||
# This data is by no means authoritative; if you think you know better,
|
||
# go ahead and edit the file (and please send any changes to
|
||
# tz@iana.org for general use in the future).
|
||
|
||
# From Paul Eggert (2006-03-22):
|
||
# 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).
|
||
#
|
||
# 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.
|
||
# Corrections are welcome!

# We just checked with our Sao Paulo office and they say the government of

#
|

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

# de la Rua on March 2, 2000, because it would make people spend more energy

# in the winter time, rather than less. The change took effect on March 3.

# 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

||
# <a href="http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834">

||
# http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
|
||
# </a>
|
||
# 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...

|

# inhabitants) will have to turn back one hour their clocks
|

#
|

# 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

# yes...I can confirm this...and given that San Luis keeps calling

|

|

# 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.

|
||
|
||
# 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:

|
||
|
||
# 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.

|
||
# </a>
|
||
#
|
||
# 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.

# 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):

# http://www.horaoficial.cl/cambio.htm
|

|
||
# 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

# <http://www.horaoficial.cl/horaof.htm> (2006-09-20), transcribed by
|
||
# Jesper Norgaard Welen. The data for Pacific/Easter are from Shanks
|
||
# & Pottenger, except with DST transitions after 1932 cloned from
|
||
# America/Santiago. The pre-1980 Pacific/Easter data are dubious,

# 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

# 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

# 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):
