Reinaldo Goulart, a Sao Paulo businessman active in 39# the railroad sector, writes (1999-07-06): 40# The subject of time zones is currently a matter of discussion/debate in 41# Brazil. Let's say that "the Brasilia time" is considered the 42# "official time" because Brasilia is the capital city. 43# The other three time zones are called "Brasilia time "minus one" or 44# "plus one" or "plus two". As far as I know there is no such 45# name/designation as "Eastern Time" or "Central Time". 46# So I invented the following (English-language) abbreviations for now. 47# Corrections are welcome! 48# std dst 49# -2:00 FNT FNST Fernando de Noronha 50# -3:00 BRT BRST Brasilia 51# -4:00 AMT AMST Amazon 52# -5:00 ACT ACST Acre 53 54############################################################################### 55 56############################################################################### 57 58# Argentina 59 60# From Bob Devine (1988-01-28): 61# Argentina: first Sunday in October to first Sunday in April since 1976. 62# Double Summer time from 1969 to 1974.

Each issue from then until 676# 9/95 says that DST is observed only in the ten states I quoted from 9/95, 677# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 678# (UTC-4).... The other two time zones given for Brazil are BR3, which is 679# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is 680# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's 681# become part of the state of Pernambuco). The boundary between BR1 and BR2 682# has never been clearly stated. They've simply been called East and West. 683# However, some conclusions can be drawn from another IATA manual: the Airline 684# Coding Directory, which lists close to 400 airports in Brazil. For each 685# airport it gives a time zone which is coded to the SSIM. From that 686# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE), 687# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do 688# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST. 689 690# From Marcos Tadeu (1998-09-27): 691# <a href="http://pcdsh01.on.br/verao1.html"> 692# Brazilian official page 693# </a> 694 695# From Jesper Norgaard (2000-11-03): 696# [For an official list of which regions in Brazil use which time zones, see:] 697# http://pcdsh01.on.br/Fusbr.htm 698# http://pcdsh01.on.br/Fusbrhv.htm 699 700# From Celso Doria via David Madeo (2002-10-09): 701# The reason for the delay this year has to do with elections in Brazil. 702# 703# Unlike in the United States, elections in Brazil are 100% computerized and 704# the results are known almost immediately.

The 2nd round will 709# take place on October 27th. 710# 711# The reason why the DST will only begin November 3rd is that the thousands 712# of electoral machines used cannot have their time changed, and since the 713# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM, 714# the Government decided to postpone DST, instead of changing the Constitution 715# (maybe, for the next elections, it will be possible to change the clock)... 716 717# From Rodrigo Severo (2004-10-04): 718# It's just the biannual change made necessary by the much hyped, supposedly 719# modern Brazilian eletronic voting machines which, apparently, can't deal 720# with a time change between the first and the second rounds of the elections. 721 722# From Steffen Thorsen (2007-09-20): 723# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00: 724# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975 725 726# From Paul Schulze (2008-06-24): 727# ...by law number 11.662 of April 24, 2008 (published in the "Diario 728# Oficial da Uniao"...) in Brazil there are changes in the timezones, 729# effective today (00:00am at June 24, 2008) as follows: 730# 731# a) The timezone UTC+5 is e[x]tinguished, with all the Acre state and the 732# part of the Amazonas state that had this timezone now being put to the 733# timezone UTC+4 734# b) The whole Para state now is put at timezone UTC+3, instead of just 735# part of it, as was before. 736# 737# This change follows a proposal of senator Tiao Viana of Acre state, that 738# proposed it due to concerns about open television channels displaying 739# programs inappropriate to youths in the states that had the timezone 740# UTC+5 too early in the night.

However for various reasons many people in the Camp have 1427# started to use daylight saving (known locally as 'Stanley Time') 1428# There is no rule as to who uses daylight saving - it is a matter of 1429# personal choice and so it is impossible to draw a map showing who 1430# uses it and who does not. Any list would be out of date as soon as 1431# it was produced. This year daylight saving ended on April 18/19th 1432# and started again on September 12/13th. I do not know what the rule 1433# is, but can find out if you like. We do not change at the same time 1434# as UK or Chile." 1435# 1436# I did have in my notes that the rule was "Second Saturday in Sep at 1437# 0:00 until third Saturday in Apr at 0:00". I think that this does 1438# not agree in some cases with Shanks; is this true? 1439# 1440# Also, there is no mention in the list that some areas in the 1441# Falklands do not use DST. I have found in my communications there 1442# that these areas are on the western half of East Falkland and all of 1443# West Falkland. Stanley is the only place that consistently observes 1444# DST. Again, as in other places in the world, the farmers don't like 1445# it. West Falkland is almost entirely sheep farmers. 1446# 1447# I know one lady there that keeps a list of which farm keeps DST and 1448# which doesn't each year.
