# This data is by no means authoritative; if you think you know better,
# go ahead and edit the file (and please send any changes to
# tz@elsie.nci.nih.gov for general use in the future).

# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# 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).
# Except where otherwise noted, it is the source for the data below.
#
# I invented the abbreviations marked `*' in the following table;
# the rest are from earlier versions of this file, or from other sources.
# Some of these are just plausible excuses for common English abbreviations.
# Corrections are welcome!

# From Guy Harris:
# From Official Airline Guide - Worldwide Edition (1987).  Countries not
# listed here do not observe DST, according to the OAG.  Time zone names
# are pure inventions, and none are supplied for countries not observing
# DST; updates from natives would be appreciated.  The times that DST
# starts and ends are based on the assumption that they switch a 2AM just
# as everybody else does.

# Brazil

# From Guy Harris:
# The OAG lists October 25, 1987 and February 12, 1988 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.
# "Brazil/Acre" is for the Territory of Acre; "Brazil/DeNoronha" is for
# Fernando De Noronha.

# From Bob Devine (January 28, 1988):
# The only information I found is that there was no DST up to 1985.
# But there was some before 1952!

# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# 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.
