# 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!

# From Peter Gradelski via Steffen Thorsen (2000-03-01):

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

# So Buenos Aires should be -3 hours from GMT at all times.

#

# 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 Mariano Absatz (2001-06-06):

# one of the major newspapers here in Argentina said that the 1999

# Timezone Law (which never was effectively applied) will (would?) be

# in effect.... The article is at

# http://ar.clarin.com/diario/2001-06-06/e-01701.htm

# ... The Law itself is "Ley No 25155", sanctioned on 1999-08-25, enacted

# 1999-09-17, and published 1999-09-21.  The official publication is at:

# Apparently it will do so on Sunday 24th....

# http://ar.clarin.com/diario/2001-06-12/s-03501.htm

#

# (2001-06-25):

# Last Friday (yes, the last working day before the date of the change), the

# Senate annulled the 1999 law that introduced the changes later postponed.

# http://www.clarin.com.ar/diario/2001-06-22/s-03601.htm

# It remains the vote of the Deputies..., but it will be the same....

# This kind of things had always been done this way in Argentina.

# We are still -03:00 all year round in all of the country.

#

# From Steffen Thorsen (2007-12-21):

# A user (Leonardo Chaim) reported that Argentina will adopt DST....

# all of the country (all Zone-entries) are affected.  News reports like

# http://www.lanacion.com.ar/opinion/nota.asp?nota_id=973037 indicate

# that Argentina will use DST next year as well, from October to

# March, although exact rules are not given.

#

# From Jesper Norgaard Welen (2007-12-26)

# The last hurdle of Argentina DST is over, the proposal was approved in

# the lower chamber too (Deputados) with a vote 192 for and 2 against.

# By the way thanks to Mariano Absatz and Daniel Mario Vega for the link to

# the original scanned proposal, where the dates and the zero hours are

# clear and unambiguous...This is the article about final approval:

# From Paul Eggert (2007-12-22):

# For dates after mid-2008, the following rules are my guesses and

# are quite possibly wrong, but are more likely than no DST at all.

# From Alexander Krivenyshev (2008-09-05):

# As per message from Carlos Alberto Fonseca Arauz (Nicaragua),

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

# Catamarca, Chubut, La Rioja, San Juan, San Luis, Santa Cruz,

# 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

# 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

# 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 says:

#  (...) anunci� que el pr�ximo domingo a las 00:00 los puntanos deber�n

# atrasar una hora sus relojes.

#

# A partir de entonces, San Luis establecer� el huso horario propio de

# la Provincia. De esta manera, durante el periodo del calendario anual

# domingo de marzo y las 24:00 del segundo s�bado de octubre.

# Quick&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 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.
