# 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.
