10# From Paul Eggert (2006-03-22):
11#
12# A good source for time zone historical data outside the U.S. is
13# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14# San Diego: ACS Publications, Inc. (2003).
15#
16# Gwillim Law writes that a good source
17# for recent time zone data is the International Air Transport
18# Association's Standard Schedules Information Manual (IATA SSIM),
19# published semiannually. Law sent in several helpful summaries
20# of the IATA's data after 1990.
21#
22# Except where otherwise noted, Shanks & Pottenger is the source for
23# entries through 1990, and IATA SSIM is the source for entries afterwards.
24#
25# Another source occasionally used is Edward W. Whitman, World Time Differences,
26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27# I found in the UCLA library.
28#
29# A reliable and entertaining source about time zones is
30# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
31#
32# Previous editions of this database used WAT, CAT, SAT, and EAT
33# for +0:00 through +3:00, respectively,
34# but Mark R V Murray reports that
35# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
36# `CAT' is commonly used for +2:00 in countries north of South Africa, and
37# `WAT' is probably the best name for +1:00, as the common phrase for
38# the area that includes Nigeria is ``West Africa''.
39# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
40#
41# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
42# I'd guess that this was because people needed _some_ name for -1:00,
43# and at the time, far west Africa was the only major land area in -1:00.
44# This usage is now obsolete, as the last use of -1:00 on the African
45# mainland seems to have been 1976 in Western Sahara.
46#
47# To summarize, the following abbreviations seem to have some currency:
48# -1:00 WAT West Africa Time (no longer used)
49# 0:00 GMT Greenwich Mean Time
50# 2:00 CAT Central Africa Time
51# 2:00 SAST South Africa Standard Time
52# and Murray suggests the following abbreviation:
53# 1:00 WAT West Africa Time
54# I realize that this leads to `WAT' being used for both -1:00 and 1:00
55# for times before 1976, but this is the best I can think of
56# until we get more information.
57#
58# I invented the following abbreviations; corrections are welcome!
59# 2:00 WAST West Africa Summer Time
60# 2:30 BEAT British East Africa Time (no longer used)
61# 2:44:45 BEAUT British East Africa Unified Time (no longer used)
62# 3:00 CAST Central Africa Summer Time (no longer used)
63# 3:00 SAST South Africa Summer Time (no longer used)
64# 3:00 EAT East Africa Time
65# 4:00 EAST East Africa Summer Time (no longer used)

232# From Abdelrahman Hassan (2007-09-06):
233# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
234# than the year of the Gregorian calendar, Ramadan shifts earlier each
235# year. This year it will be observed September 13 (September is quite
236# hot in Egypt), and the idea is to make fasting easier for workers by
237# shifting business hours one hour out of daytime heat. Consequently,
238# unless discontinued, next DST may end Thursday 28 August 2008.

450# From Steffen Thorsen (2008-07-10):

455# (in French), Mauritius will start and end their DST a few days earlier
456# than previously announced (2008-11-01 to 2009-03-31). The new start
457# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
458# given, but it is probably at either 2 or 3 wall clock time).
459#
460# A little strange though, since the article says that they moved the date
461# to align itself with Europe and USA which also change time on that date,
462# but that means they have not paid attention to what happened in
463# USA/Canada last year (DST ends first Sunday in November). I also wonder
464# why that they end on a Friday, instead of aligning with Europe which
465# changes two days later.
466
467# From Alex Krivenyshev (2008-07-11):
468# Seems that English language article "The revival of daylight saving

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

898# From Arthur David Olson (2009--3-18):
899# The Tunis Afrique Presse News Agency notice contains this: "This measure is due to the fact
900# that the fasting month of ramadan coincides with the period concerned by summer time.
901# Therefore, the standard time will be kept unchanged the whole year long."
902# So foregoing DST seems to be an exception (albeit one that may be repeated in the future).
