# @(#)africa 7.5
# 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.
#
# 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.
#
# I added so many Zone names that the old, mostly flat name space was unwieldy.
# So I renamed the Zones to have the form AREA/LOCATION, where
# AREA is the name of a continent or ocean, and
# LOCATION is the name of a specific location within that region.
# For example, the old zone name `Egypt' is now `Africa/Cairo'.
#
# Here are the general rules I used for choosing location names,
# in decreasing order of importance:
#
# Use only valid Posix file names. Use only Ascii letters, digits, `.',
# `-' and `_'. Do not exceed 14 characters or start with `-'.
# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
# Include at least one location per time zone rule set per country.
# One such location is enough.
# If a name is ambiguous, use a less ambiguous alternative;
# e.g. many cities are named San Jose and Georgetown, so
# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
# Keep locations compact. Use cities or small islands, not countries
# or regions, so that any future time zone changes do not split
# locations into different time zones. E.g. prefer `Paris'
# to `France', since France has had multiple time zones.
# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
# prefer `Athens' to the true name (which uses Greek letters).
# The Posix file name restrictions encourage this rule.
# Use the most populous among locations in a country's time zone,
# e.g. prefer `Shanghai' to `Beijing'. Among locations with
# similar populations, pick the best-known location,
# e.g. prefer `Rome' to `Milan'.
# Use the singular form, e.g. prefer `Canary' to `Canaries'.
# Omit common suffixes like `_Islands' and `_City', unless that
# would lead to ambiguity. E.g. prefer `Cayman' to
# `Cayman_Islands' and `Guatemala' to `Guatemala_City',
# but prefer `Mexico_City' to `Mexico' because the country
# of Mexico has several time zones.
# Use `_' to represent a space.
# Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
# to `St._Helena'.
#
# I made up the following time zone abbreviations; corrections are welcome!
# LMT Local Mean Time
# -2:00 CVT Cape Verde Time (no longer used)
# -1:00 AAT Atlantic Africa Time
# 0:00 WAT West Africa Time
# 1:00 CAT Central Africa Time
# 2:00 SAT South Africa Time
# 3:00 EAT East Africa Time
# 4:00 SMT Seychelles and Mascarene Time
# The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.

#
# 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).

# 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).

# People's Republic of China
# From Guy Harris:
# People's Republic of China. Yes, they really have only one time zone.
# From Bob Devine (January 28, 1988):
# No they don't. See TIME mag, February 17, 1986 p.52. Even though
# China is across 4 physical time zones, before Feb 1, 1986 only the
# Peking (Bejing) time zone was recognized. Since that date, China
# has two of 'em -- Peking's and Urumqi (named after the capital of
# the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
#
# . . .I just deleted the DST table and this editor makes it too
# painful to suck in another copy.. So, here is what I have for
# DST start/end dates for Peking's time zone (info from AP):
#
# 1986 May 4 - Sept 14
# 1987 mid-April - ??
# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# According to Shanks, China started using DST in 1986,
# but it's still all one big happy time zone.
# From U. S. Naval Observatory (January 19, 1989):
# CHINA 8 H AHEAD OF UTC ALL OF CHINA, INCL TAIWAN
# CHINA 9 H AHEAD OF UTC APR 17 - SEP 10
# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# Shanks writes that China switched from the Chinese calendar on 1912 Feb 12.
# He also writes that China has had a single time zone since 1980 May 1,
# and that they instituted DST on 1986 May 4; this contradicts Devine's
# note about Time magazine, though apparently _something_ happened in 1986.

# From Ephraim Silverberg (September 5, 1993):
#
# According to the Office of the Secretary General of the Ministry of
# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
# Each year they decide anew what havoc to wreak on the country. However,
# there is a "supposed" set of rules which is subject to change depending
# on the party the Minister of Interior, the size of the coalition
# government, the phase of the moon and the direction of the wind. Hence,
# changes may need to be made on a semi-annual basis. One thing is entrenched
# in law, however: that there must be at least 150 days on daylight savings
# time annually.

# `9:00' and `JST' is from Guy Harris.
# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# Shanks says that the far southern Ryukyu Is (Nansei-Shoto) are 8:00,
# but we don't have a good location name for them;
# we don't even know the name of the principal town.
# There is no information for Marcus.
# Other Japanese possessions are probably like Asia/Tokyo.
# From Shanks (1991):
# Japan switched from the Japanese calendar on 1893 Jan 1.

# Australia
# From John Mackin (March 6, 1991):
# We in Australia have _never_ referred to DST as `daylight' time.
# It is called `summer' time. Now by a happy coincidence, `summer'
# and `standard' happen to start with the same letter; hence, the
# abbreviation does _not_ change...
# The legislation does not actually define abbreviations, at least
# in this State, but the abbreviation is just commonly taken to be the
# initials of the phrase, and the legislation here uniformly uses
# the phrase `summer time' and does not use the phrase `daylight
# time'.
# Announcers on the Commonwealth radio network, the ABC (for Australian
# Broadcasting Commission), use the phrases `Eastern Standard Time'
# or `Eastern Summer Time'. (Note, though, that as I say in the
# current australasia file, there is really no such thing.) Announcers
# on its overseas service, Radio Australia, use the same phrases
# prefixed by the word `Australian' when referring to local times;
# time announcements on that service, naturally enough, are made in UTC.
# From Arthur David Olson (March 8 1992):
# Given the above, what's chosen for year-round use is:
# CST for any place operating at a GMTOFF of 9:30
# WST for any place operating at a GMTOFF of 8:00
# EST for any place operating at a GMTOFF of 10:00

# From W. Jones (jones@skdad.usask.ca) (November 6, 1992):
# The. . .below is based on information I got from our law library, the
# provincial archives, and the provincial Community Services department.
# A precise history would require digging through newspaper archives, and
# since you didn't say what you wanted, I didn't bother.
#
# Saskatchewan is split by a time zone meridian (105W) and over the years
# the boundary became pretty ragged as communities near it reevaluated
# their affiliations in one direction or the other. In 1965 a provincial
# referendum favoured legislating common time practices.
#
# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
# Saskatchewan 1978) was proclaimed, and established that the eastern
# part of Saskatchewan would use CST year round, that districts in
# northwest Saskatchewan would by default follow CST but could opt to
# follow Mountain Time rules (thus 1 hour difference in the winter and
# zero in the summer), and that districts in southwest Saskatchewan would
# by default follow MT but could opt to follow CST.
#
# It took a few years for the dust to settle (I know one story of a town
# on one time zone having its school in another, such that a mom had to
# serve her family lunch in two shifts), but presently it seems that only
# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
# rules any more; all other districts appear to have used CST year round
# since sometime in the 1960s.
#
# Here's how I would summarize things. Establish a "Saskatchewan" CST
# time zone, and note that it officially exists as of 15 April 1966. Any
# current exceptions can put themselves in the "Mountain" zone, since
# those are the rules they follow. Any past exceptions can be forgotten,
# since that's what those who live here have done.
# From Arthur David Olson (November 21, 1992):
# East-Saskatchewan kept to avoid problems for folks using that zone by name;
# plain Saskatchewan added.

# Mexico
# From Guy Harris:
# Rules are from the Official Airline Guide, Worldwide Edition, for 1987.
# Rules prior to 1987 are unknown.
# The comments in the OAG say "Only Ensenada, Mexicale, San Felipe and Tijuana
# observe DST." This is presumably Baja California Norte, above 28th parallel,
# as listed there; Mexico/BajaSur is for "Baja California Sur and N. Pacific
# Coast (States of Sinaloa and Sonora)."
# From Bob Devine (January 28, 1988):
# The Federal District (where Mexico City is) has observed [DST] several
# times but not recently.
#
# I don't where to drawn the line in the North Baja area. 28th latitude
# sounds good -- but it may be higher (how far [d]o radio stations from
# San Diego affect culture?).
#
# The dates of DST probably go back to 1981. The rules are the same as
# US's. This is going to be a headache for US presidential electi[o]n years!
# From Arthur David Olson (February 13, 1988)
# Since the 1981 starting date is only "probable," we'll keep the 1987
# starting date below.
# From U. S. Naval Observatory (January 19, 1989):
# MEXICO BAJA CAL N 7 H BEHIND UTC BAJA CALIFORNIA SUR AND
# MEXICO BAJA CAL N N. PACIFIC COAST (STATES
# MEXICO BAJA CAL N OF SINALOA AND SONORA)
# MEXICO BAJA CAL N 8 H BEHIND UTC ABOVE 28TH PARALLAL APR 3
# MEXICO BAJA CAL N - OCT 29
# MEXICO BAJA CAL N 7 H BEHIND UTC ABOVE 28TH PARALLAL APR 3
# MEXICO BAJA CAL N - 0CT 29
# MEXICO 6 H BEHIND UTC STATES OF DURANGO,
# MEXICO COAHUILA, NUEVO LEON,
# MEXICO TAMAULIPAS
# MEXICO 5 H BEHIND UTC STATES OF DURANGO,
# MEXICO COAHUILA, NUEVO LEON,
# MEXICO TAMAULIPAS APR 3 - OCT 29
# MEXICO 6 H BEHIND UTC GENERAL MEXICO, STATES OF
# MEXICO CAMPECHE, QUINTANA ROO AND
# MEXICO YUCATAN
# From Arthur David Olson (January 21, 1989):
# April 3 fell on a Sunday in 1988; October 29 fell on a Sunday in 1989. Ahem.
# USNO claims there should be four Mexican zones rather than three:
# a zone that's GMT-8 with DST; a zone that's always GMT-7;
# a zone that's GMT-6 with DST; and a zone that's always GMT-6.
# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
# Shanks also says there are four zones, but disagrees about the fourth.
# Instead of GMT-6 with DST, he says there's GMT-8 without DST.

# From Arthur David Olson (April 5, 1989):
# On April 5, 1989, the U. S. House of Representatives passed (238-154) a bill
# establishing "Pacific Presidential Election Time"; it was not acted on
# by the Senate or signed into law by the President.
# You might want to change the "PE" (Presidential Election) below to
# "Q" (Quadrennial) to maintain three-character zone abbreviations.
# If you're really conservative, you might want to change it to "D".
# Avoid "L" (Leap Year), which won't be true in 2100.
# If Presidential Election Time is ever established, replace "XXXX" below
# with the year the law takes effect and uncomment the "##" lines.

# So much for footnotes about Saudi Arabia.
# Apparent noon times below are for Riyadh; your mileage will vary.
# Times were computed using formulas in the U.S. Naval Observatory's
# Almanac for Computers 1987; the formulas "will give EqT to an accuracy of
# [plus or minus two] seconds during the current year."
#
# Rounding to the nearest five seconds results in fewer than
# 256 different "time types"--a limit that's faced because time types are
# stored on disk as unsigned chars.

# Apparent noon times below are for Riyadh; they're a bit off for other places.
# Times were computed using formulas in the U.S. Naval Observatory's
# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
# [plus or minus two] seconds during the current year."
#
# Rounding to the nearest five seconds results in fewer than
# 256 different "time types"--a limit that's faced because time types are
# stored on disk as unsigned chars.

# @(#)solar89 7.2
# Apparent noon times below are for Riyadh; they're a bit off for other places.
# Times were computed using a formula provided by the U. S. Naval Observatory:
# eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
# -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
# + 19.3 * cos(3 * l);
# where l is the "mean longitude of the Sun" given by
# l = 279.642 degrees + 0.985647 * d
# and d is the interval in days from January 0, 0 hours Universal Time
# (equaling the day of the year plus the fraction of a day from zero hours).
# The accuracy of the formula is plus or minus three seconds.
#
# Rounding to the nearest five seconds results in fewer than
# 256 different "time types"--a limit that's faced because time types are
# stored on disk as unsigned chars.

# 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

# 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.
