# Oxford University Press (1980).
#
# 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'.
# 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.
#
# Here are the general rules I used for choosing location names,
# in decreasing order of importance:
# 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.
#
# 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 all the clocks in a country's region have agreed since 1970,
# don't bother to include more than one location
# even if subregions' clocks disagreed before 1970.
# Otherwise these tables would become annoyingly large.
# 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'.
# 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.
#
# For time zone abbreviations like `EST' I used the following rules,
# in decreasing order of importance:
#
# Use abbreviations that consist of 3 or more upper-case Ascii letters,
# except use "___" for locations while uninhabited.
# Posix.1 requires at least 3 characters, and the restriction to
# upper-case Ascii letters follows most traditions.
# Previous editions of this database also used characters like
# ' ' and '?', but these characters have a special meaning to
# the shell and cause commands like
# set `date`
# to have unexpected effects. In theory, the character set could
# be !%./@A-Z^_a-z{}, but these tables use only upper-case
# Ascii letters (and "___").
# Use abbreviations that are in common use among English-speakers,
# e.g. `EST' for Eastern Standard Time in North America.
# We assume that applications translate them to other languages
# as part of the normal localization process; for example,
# a French application might translate `EST' to `HNE'.
# For zones whose times are taken from a city's longitude, use the
# traditional xMT notation, e.g. `PMT' for Paris Mean Time.
# The only name like this in current use is `GMT'.
# If there is no common English abbreviation, abbreviate the English
# translation of the usual phrase used by native speakers.
# If this is not available or is a phrase mentioning the country
# (e.g. ``Cape Verde Time''), then:
#
# When a country has a single or principal time zone region,
# append `T' to the country's ISO code, e.g. `CVT' for
# Cape Verde Time. For summer time append `ST';
# for double summer time append `DST'; etc.
# When a country has multiple time zones, take the first three
# letters of an English place name identifying each zone
# and then append `T', `ST', etc. as before;
# e.g. `MOSST' for MOScow Summer Time.
#
#
# For Africa I invented the following time zone abbreviations.
# LMT Local Mean Time
# -1:00 AAT Atlantic Africa Time (no longer used)
# 0:00 WAT West Africa Time
# 1:00 CAT Central Africa Time
# 2:00 SAT South Africa Time
# 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
# 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.
# 4:00 EAST East Africa Summer Time (no longer used)
