-04 607 608# Brazil 609 610# From Paul Eggert (1993-11-18): 611# The mayor of Rio recently attempted to change the time zone rules 612# just in his city, in order to leave more summer time for the tourist trade. 613# The rule change lasted only part of the day; 614# the federal government refused to follow the city's rules, and business 615# was in a chaos, so the mayor backed down that afternoon. 616 617# From IATA SSIM (1996-02): 618# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS), 619# Santa Catarina (SC), Paran�� (PR), S��o Paulo (SP), Rio de Janeiro (RJ), 620# Esp��rito Santo (ES), Minas Gerais (MG), Bahia (BA), Goi��s (GO), 621# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL]. 622# [The last three states are new to this issue of the IATA SSIM.] 623 624# From Gwillim Law (1996-10-07): 625# Geography, history (Tocantins was part of Goi��s until 1989), and other 626# sources of time zone information lead me to believe that AL, SE, and TO were 627# always in BR1, and so the only change was whether or not they observed DST.... 628# The earliest issue of the SSIM I have is 2/91. Each issue from then until 629# 9/95 says that DST is observed only in the ten states I quoted from 9/95, 630# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2 631# (UTC-4).... The other two time zones given for Brazil are BR3, which is 632# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is 633# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's 634# become part of the state of Pernambuco). The boundary between BR1 and BR2 635# has never been clearly stated. They've simply been called East and West. 636# However, some conclusions can be drawn from another IATA manual: the Airline 637# Coding Directory, which lists close to 400 airports in Brazil. For each 638# airport it gives a time zone which is coded to the SSIM. From that 639# information, I'm led to conclude that the states of Amap�� (AP), Cear�� (CE), 640# Maranh��o (MA), Para��ba (PR), Pernambuco (PE), Piau�� (PI), and Rio Grande do 641# Norte (RN), and the eastern part of Par�� (PA) are all in BR1 without DST. 642 643# From Marcos Tadeu (1998-09-27): 644# Brazilian official page <http://pcdsh01.on.br/verao1.html> 645 646# From Jesper N��rgaard (2000-11-03): 647# [For an official list of which regions in Brazil use which time zones, see:] 648# http://pcdsh01.on.br/Fusbr.htm 649# http://pcdsh01.on.br/Fusbrhv.htm 650 651# From Celso Doria via David Madeo (2002-10-09): 652# The reason for the delay this year has to do with elections in Brazil. 653# 654# Unlike in the United States, elections in Brazil are 100% computerized and 655# the results are known almost immediately. Yesterday, it was the first 656# round of the elections when 115 million Brazilians voted for President, 657# Governor, Senators, Federal Deputies, and State Deputies. Nobody is 658# counting (or re-counting) votes anymore and we know there will be a second 659# round for the Presidency and also for some Governors. The 2nd round will 660# take place on October 27th. 661# 662# The reason why the DST will only begin November 3rd is that the thousands 663# of electoral machines used cannot have their time changed, and since the 664# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM, 665# the Government decided to postpone DST, instead of changing the Constitution 666# (maybe, for the next elections, it will be possible to change the clock)... 667 668# From Rodrigo Severo (2004-10-04): 669# It's just the biannual change made necessary by the much hyped, supposedly 670# modern Brazilian eletronic voting machines which, apparently, can't deal 671# with a time change between the first and the second rounds of the elections. 672 673# From Steffen Thorsen (2007-09-20): 674# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00: 675# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975 676 677# From Paul Schulze (2008-06-24): 678# ...by law number 11.662 of April 24, 2008 (published in the "Diario 679# Oficial da Uni��o"...) in Brazil there are changes in the timezones, 680# effective today (00:00am at June 24, 2008) as follows: 681# 682# a) The timezone UTC+5 is extinguished, with all the Acre state and the 683# part of the Amazonas state that had this timezone now being put to the 684# timezone UTC+4 685# b) The whole Par�� state now is put at timezone UTC+3, instead of just 686# part of it, as was before. 687# 688# This change follows a proposal of senator Tiao Viana of Acre state, that 689# proposed it due to concerns about open television channels displaying 690# programs inappropriate to youths in the states that had the timezone 691# UTC+5 too early in the night. In the occasion, some more corrections 692# were proposed, trying to unify the timezones of any given state.

Go with [2], rounding it to -4:42:46. 1125# 1126# - [1] says the 1918 transition was Sep 1, [2] says Sep 10 and cites 1127# Bolet��n No. 22, Aviso No. 129/1918 (1918-08-23). Go with [2]. 1128# 1129# - [1] does not give times for transitions; assume they occur 1130# at midnight mainland time, the current common practice. However, 1131# go with [2]'s specification of 23:00 for the 1947-05-21 transition. 1132# 1133# Another correction to [1] is from Jesper N��rgaard Welen, who 1134# wrote (2006-10-08), "I think that there are some obvious mistakes in 1135# the suggested link from Oscar van Vlijmen,... for instance entry 66 1136# says that GMT-4 ended 1990-09-12 while entry 67 only begins GMT-3 at 1137# 1990-09-15 (they should have been 1990-09-15 and 1990-09-16 1138# respectively), but anyhow it clears up some doubts too." 1139# 1140# Data for Pacific/Easter from 1910 through 1967 come from Shanks & 1141# Pottenger.
