# 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> (1997-10-05):
#
# A good source for time zone historical data outside the U.S. is
# Thomas G. Shanks, The International Atlas (4th edition),
# San Diego: ACS Publications, Inc. (1995).
#
# 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,
# and IATA SSIM is the source for entries after 1990.
#
# Another source occasionally used is Edward W. Whitman, World Time Differences,
# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
# I found in the UCLA library.
#
# A reliable and entertaining source about time zones is
# Derek Howse, Greenwich time and the discovery of the longitude,
# Oxford University Press (1980).
#
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for +0:00 through +3:00, respectively,
# but Mark R V Murray <markm@iafrica.com> reports that
# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
# `CAT' is commonly used for +2:00 in countries north of South Africa, and
# `WAT' is probably the best name for +1:00, as the common phrase for
# the area that includes Nigeria is ``West Africa''.
# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
#
# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
# I'd guess that this was because people needed _some_ name for -1:00,
# and at the time, far west Africa was the only major land area in -1:00.
# This usage is now obsolete, as the last use of -1:00 on the African
# mainland seems to have been 1976 in Western Sahara.
#
# To summarize, the following abbreviations seem to have some currency:
#	-1:00	WAT	West Africa Time (no longer used)
#	 0:00	GMT	Greenwich Mean Time
#	 2:00	CAT	Central Africa Time
#	 2:00	SAST	South Africa Standard Time
# and Murray suggests the following abbreviation:
#	 1:00	WAT	West Africa Time
# I realize that this leads to `WAT' being used for both -1:00 and 1:00
# for times before 1976, but this is the best I can think of
# until we get more information.
#
# I invented the following abbreviations; corrections are welcome!
#	 2:00	WAST	West Africa Summer Time
#	 2:30	BEAT	British East Africa Time (no longer used)
#	 2:45	BEAUT	British East Africa Unified Time (no longer used)
#	 3:00	CAST	Central Africa Summer Time (no longer used)
#	 3:00	SAST	South Africa Summer Time (no longer used)
#	 3:00	EAT	East Africa Time
#	 4:00	EAST	East Africa Summer Time (no longer used)

# but this is most likely a typo for 5W42, the longitude of Jamestown.
