# 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 (2006-03-22):
#
# A good source for time zone historical data outside the U.S. is
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
# San Diego: ACS Publications, Inc. (2003).
#
# Gwillim Law 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 & Pottenger is the source for
# entries through 1990, and IATA SSIM is the source for entries afterwards.
#
# 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 longitude, Philip Wilson Publishers (1997).
#
# Previous editions of this database used WAT, CAT, SAT, and EAT
# for +0:00 through +3:00, respectively,
# but Mark R V Murray 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)
#	 2:44:45 BEAUT	British East Africa Unified Time (no longer used)
#	 3:00	CAST	Central Africa Summer Time (no longer used)

# <http://allafrica.com/stories/200703300178.html>:
# While the entire country changes its time, Katima Mulilo and other
# settlements in Caprivi unofficially will not because the sun there
# rises and sets earlier compared to other regions.  Chief of
# Forecasting Riaan van Zyl explained that the far eastern parts of
# the country are close to 40 minutes earlier in sunrise than the rest
# of the country.
# 
# From Paul Eggert (2007-03-31):
# Apparently the Caprivi Strip informally observes Botswana time, but
# we have no details.  In the meantime people there can use Africa/Gaborone.

# From Gwillim Law (2005-04-30):
# My correspondent, Risto Nykanen, has alerted me to another adoption of DST,
# this time in Tunisia.  According to Yahoo France News
# <http://fr.news.yahoo.com/050426/5/4dumk.html>, in a story attributed to AP
# and dated 2005-04-26, "Tunisia has decided to advance its official time by
# one hour, starting on Sunday, May 1.  Henceforth, Tunisian time will be
# UTC+2 instead of UTC+1.  The change will take place at 23:00 UTC next
# Saturday."  (My translation)
