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.
