+# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks, The International Atlas (3rd edition),
+# San Diego: ACS Publications, Inc. (1991).
+#
+# Gwillim Law <LAW@encmail.encompass.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,

+# 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.

+# From Official Airline Guide - Worldwide Edition (1987).  Countries not

+# are pure inventions, and none are supplied for countries not observing
+# DST; updates from natives would be appreciated.  The times that DST

+# From Guy Harris:
+# The OAG lists 1987-10-25 and 1988-02-12 as the starting and
+# ending dates, giving them as "estimated date(s) based on previous year".  We
+# infer a rule here from one example, always a dangerous practice....  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 <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 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 <feher@pobox.com> (1998-01-17):
+# Reading "southamerica" file in timezone 7.55 I've found an
+# error. Line 193 say "Territory of Acre". It is not a territory anymore
+# but a state.
