# In 1929 the Soviet Union instituted a 5 day week; in 1932 it instituted
# a 6 day week; on 1940-06-27 it returned to the Gregorian week.
#
# From Paul Eggert <eggert@twinsun.com> (1996-09-03):
# Moscow rules after 1991 are from Andrew A. Chernov <ache@astral.msk.su>.
# I invented the time zone names, and (unless otherwise specified)
# guessed what happened after 1991; the clocks were chaotic, and we know little.
# The rest is from Shanks.
# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
# Except for Moscow after 1919-07-01, I invented the time zone abbreviations,
# and (unless otherwise specified) guessed what happened after 1991.
# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
# are from Andrey A. Chernov. The rest is from Shanks and the IATA.
#
# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
# `MSK' and `MSD' were born and used initially on Moscow computers with
# Unix-like OSes by several developer groups (e.g. Demos group, Kiae group)....
# The next step was the UUCP network, the Relcom predecessor
# (used mainly for mail), and MSK/MSD was actively used there.
#
# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):
# According to a friend of mine who rode the Trans-Siberian Railroad from
# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
# still follows Moscow time, no matter where in Russia it is located.

# "[America/Porto_Acre]" is for the Territory of Acre;

# From Bob Devine (1988-01-28):

# But there was some before 1952!

# BRAZIL 3 H BEHIND UTC FOR MOST MAJOR AIRPORTS.
# 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.
# Shanks claims Acre stopped observing DST after 1988 Feb 7, but it
# could just be that his table ran out of room. We're extrapolating
# about time zone changes after 1990 Feb 11.
# 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.
