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

2N/A# From Abdelrahman Hassan (2007-09-06):
2N/A# Due to the Hijri (lunar Islamic calendar) year being 11 days shorter

2N/A# year. This year it will be observed September 13 (September is quite
2N/A# hot in Egypt), and the idea is to make fasting easier for workers by
2N/A# shifting business hours one hour out of daytime heat. Consequently,
2N/A# unless discontinued, next DST may end Thursday 28 August 2008.

2N/A# From Steffen Thorsen (2008-06-25):
2N/A# Mauritius plans to observe DST from 2008-11-01 to 2009-03-31 on a trial
2N/A# It seems that Mauritius observed daylight saving time from 1982-10-10 to
2N/A# 1983-03-20 as well, but that was not successful....
2N/A# From Alex Krivenyshev (2008-06-25):
2N/A# From Arthur David Olson (2008-06-30):
2N/A# final decision has yet to be made on the times that daylight saving
2N/A# would begin and end on these dates." As a place holder, use midnight.
2N/A# From Paul Eggert (2008-06-30):
2N/A# Follow Thorsen on DST in 1982/1983, instead of Shanks & Pottenger.
2N/A# From Steffen Thorsen (2008-07-10):
2N/A# (in French), Mauritius will start and end their DST a few days earlier
2N/A# than previously announced (2008-11-01 to 2009-03-31). The new start
2N/A# date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
2N/A# given, but it is probably at either 2 or 3 wall clock time).
2N/A# A little strange though, since the article says that they moved the date
2N/A# to align itself with Europe and USA which also change time on that date,
2N/A# but that means they have not paid attention to what happened in
2N/A#
USA/Canada last year (DST ends first Sunday in November). I also wonder
2N/A# why that they end on a Friday, instead of aligning with Europe which
2N/A# changes two days later.
2N/A# From Alex Krivenyshev (2008-07-11):
2N/A# Seems that English language article "The revival of daylight saving
2N/A# time: Energy conservation?"-# No. 16578 (07/11/2008) was originally
2N/A# published on Monday, June 30, 2008...
2N/A# I guess that article in French "Le gouvernement avance l'introduction
2N/A# de l'heure d'ete" stating that DST in Mauritius starting on October 26
2N/A# and ending on March 27, 2009 is the most recent one.
2N/A# From Riad M. Hossen Ally (2008-08-03):
2N/A# The Government of Mauritius weblink
2N/A# Cabinet Decision of July 18th, 2008 states as follows:
2N/A# 4.
...Cabinet has agreed to the introduction into the National Assembly
2N/A# of the Time Bill which provides for the introduction of summer time in
2N/A# Mauritius. The summer time period which will be of one hour ahead of
2N/A# the standard time, will be aligned with that in Europe and the United
2N/A# States of America. It will start at two o'clock in the morning on the
2N/A# last Sunday of October and will end at two o'clock in the morning on
2N/A# the last Sunday of March the following year. The summer time for the
2N/A# year 2008 - 2009 will, therefore, be effective as from 26 October 2008
2N/A# and end on 29 March 2009.
2N/A# From Ed Maste (2008-10-07):
2N/A# THE TIME BILL (No. XXVII of 2008) Explanatory Memorandum states the
2N/A# beginning / ending of summer time is 2 o'clock standard time in the

2N/A# Here is an article that Morocco plan to introduce Daylight Saving Time between
2N/A# 1 June, 2008 and 27 September, 2008.
2N/A# "... Morocco is to save energy by adjusting its clock during summer so it will
2N/A# be one hour ahead of GMT between 1 June and 27 September, according to
2N/A# Communication Minister and Gov ernment Spokesman, Khalid Naciri...."
2N/A# From Alex Krivenyshev (2008-05-09):
2N/A# The Morocco time change can be confirmed on Morocco web site Maghreb Arabe Presse:
2N/A# Morocco shifts to daylight time on June 1st through September 27, Govt.
2N/A# From Patrice Scattolin (2008-05-09):
2N/A# According to this article:
2N/A# (and republished here:
2N/A# the changes occurs at midnight:
2N/A# saturday night may 31st at midnight (which in french is to be
2N/A# intrepreted as the night between saturday and sunday)
2N/A# sunday night the 28th at midnight
2N/A# Seeing that the 28th is monday, I am guessing that she intends to say
2N/A# the midnight of the 28th which is the midnight between sunday and
2N/A# monday, which jives with other sources that say that it's inclusive
2N/A# june1st to sept 27th.
2N/A# The decision was taken by decree *2-08-224 *but I can't find the decree
2N/A# published on the web.
2N/A# It's also confirmed here:
2N/A# on a government portal as being between june 1st and sept 27th (not yet
2N/A# posted in english).
2N/A# The following google query will generate many relevant hits:
2N/A# From Alex Krivenyshev (2008-05-09):
2N/A# Is Western Sahara (part which administrated by Morocco) going to follow
2N/A# Morocco DST changes? Any information? What about other part of
2N/A# Western Sahara - under administration of POLISARIO Front (also named
2N/A# SADR Saharawi Arab Democratic Republic)?
2N/A# From Arthur David Olson (2008-05-09):
2N/A# XXX--guess that it is only Morocco for now; guess only 2008 for now.
2N/A# From Steffen Thorsen (2008-08-27):
2N/A# Morocco will change the clocks back on the midnight between August 31
2N/A# and September 1. They originally planned to observe DST to near the end
2N/A# One article about it (in French):
2N/A# We have some further details posted here:
2N/A# From Steffen Thorsen (2009-03-17):
2N/A# Morocco will observe DST from 2009-06-01 00:00 to 2009-08-21 00:00 according
2N/A# to many sources, such as
2N/A# From Alexander Krivenyshev (2009-03-17):
2N/A# Here is a link to official document from Royaume du Maroc Premier Ministre,
2N/A# Ministere de la Modernisation des Secteurs Publics
2N/A# Under Article 1 of Royal Decree No. 455-67 of Act 23 safar 1387 (2 june 1967)
2N/A# concerning the amendment of the legal time, the Ministry of Modernization of
2N/A# Public Sectors announced that the official time in the Kingdom will be
2N/A# advanced 60 minutes from Sunday 31 May 2009 at midnight.
2N/A# From Steffen Thorsen (2010-04-13):
2N/A# Several news media in Morocco report that the Ministry of Modernization
2N/A# of Public Sectors has announced that Morocco will have DST from
2N/A# 2010-05-02 to 2010-08-08.
2N/A# From Dan Abitol (2011-03-30):
2N/A# The 3rd april 2011 at 00:00:00, [it] will be 3rd april 1:00:00
2N/A# The 31th july 2011 at 00:59:59, [it] will be 31th July 00:00:00
2N/A# The change was broadcast on the FM Radio
2N/A# I ve called ANRT (telecom regulations in Morocco) at
2N/A# is the official publication to look at.
2N/A# They said that the decision was already taken.
2N/A# More articles in the press
2N/A# From Petr Machata (2011-03-30):
2N/A# They have it written in English here:
2N/A# It says there that "Morocco will resume its standard time on July 31,
2N/A# 2011 at midnight." Now they don't say whether they mean midnight of
2N/A# wall clock time (
i.e. 11pm UTC), but that's what I would assume. It has
2N/A# also been like that in the past.

2N/A# From Gwillim Law (2005-04-30):
2N/A# My correspondent, Risto Nykanen, has alerted me to another adoption of DST,
2N/A# this time in Tunisia. According to Yahoo France News
2N/A# and dated 2005-04-26, "Tunisia has decided to advance its official time by
2N/A# one hour, starting on Sunday, May 1. Henceforth, Tunisian time will be
2N/A# UTC+2 instead of UTC+1. The change will take place at 23:00 UTC next
2N/A# Saturday." (My translation)

2N/A# LaPresse, the first national daily newspaper ...
2N/A# ... DST for 2005: on: Sun May 1 0h standard time, off: Fri Sept. 30,
2N/A# From Atef Loukil (2006-03-28):
2N/A# The daylight saving time will be the same each year:
2N/A# Beginning : the last Sunday of March at 02:00
2N/A# Ending : the last Sunday of October at 03:00 ...
2N/A# From Steffen Thorsen (2009-03-16):
2N/A# According to several news sources, Tunisia will not observe DST this year.
2N/A# We have also confirmed this with the US embassy in Tunisia.
2N/A# We have a wrap-up about this on the following page:
2N/A# From Alexander Krivenyshev (2009-03-17):
2N/A# Here is a link to Tunis Afrique Presse News Agency
2N/A# From Arthur David Olson (2009--3-18):
2N/A# The Tunis Afrique Presse News Agency notice contains this: "This measure is due to the fact
2N/A# that the fasting month of ramadan coincides with the period concerned by summer time.
2N/A# Therefore, the standard time will be kept unchanged the whole year long."
2N/A# So foregoing DST seems to be an exception (albeit one that may be repeated in the future).
2N/A# From Alexander Krivenyshev (2010-03-27):
2N/A# According to some news reports Tunis confirmed not to use DST in 2010
2N/A# "The Tunisian government has decided to abandon DST, which was scheduled on
2N/A# Tunisian authorities had suspended the DST for the first time last year also
