Yes, +# they really do switch on Saturday, according to the OAG. +# "[America/Porto_Acre]" is for the [State] of Acre; +# "[America/Noronha]" is for Fernando De Noronha. + +# 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 Paul Eggert (1996-11-22): +# Let's make the following assumptions: +# +# * All data in Shanks are correct through 1990. In particular, +# Shanks was right when he said Acre stopped observing DST in mid-1988. +# * Areas where Shanks reports DST up to 1990, but the IATA reports no DST +# in 1995, stopped observing DST in mid-1990. +# +# Under these assumptions Brazil needs 7 entries to cover all the distinct +# time zone histories since 1970: +# +# Noronha (UTC-2), Fortaleza (UTC-3), and Manaus (UTC-4) stopped observing DST +# in mid-1990. +# Maceio (UTC-3) stopped observing DST in mid-1990, but started again mid-1995. +# Sao Paulo (UTC-3) and Cuiaba (UTC-4) always observed DST. +# Porto Acre (UTC-5) stopped observing DST in mid-1988. + +# From Rodrigo Feher (1998-01-17): +# Reading "southamerica" file in timezone 7.55 I've found an +# error.
