|
|
|
|
# From Paul Eggert <eggert@twinsun.com> (1999-07-07):
|
|
# A good source for time zone historical data outside the U.S. is
|
|
# Thomas G. Shanks, The International Atlas (5th edition),
|
|
# San Diego: ACS Publications, Inc. (1999).
|
|
#
|
|
# Gwillim Law <Gwil_Law@bridge-point.com> 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 is the source for entries through 1990,
|
|
# and IATA SSIM is the source for entries after 1990.
|
|
#
|
|
# 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 Paul Eggert <eggert@twinsun.com> (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 Daniel C. Sobral <dcs@gns.com.br> (1998-02-12):
|
|
# In 1997, the DS began on October 6. The stated reason was that
|
|
# because international television networks ignored Brazil's policy on DS,
|
|
# they bought the wrong times on satellite for coverage of Pope's visit.
|
|
# This year, the ending date of DS was postponed to March 1
|
|
# to help dealing with the shortages of electric power.
