7# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (3rd edition),
11# San Diego: ACS Publications, Inc. (1991).
12# Except where otherwise noted, it is the source for the data below.
13#
14# Another source occasionally used is Edward W. Whitman, World Time Differences,
15# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
16# I found in the UCLA library.
17#
18# A reliable and entertaining source about time zones is
19# Derek Howse, Greenwich time and the discovery of the longitude,
20# Oxford University Press (1980).
21#
22# I added so many Zone names that the old, mostly flat name space was unwieldy.
23# So I renamed the Zones to have the form AREA/LOCATION, where
24# AREA is the name of a continent or ocean, and
25# LOCATION is the name of a specific location within that region.
26# For example, the old zone name `Egypt' is now `Africa/Cairo'.
27#
28# Here are the general rules I used for choosing location names,
29# in decreasing order of importance:
30#
31# Use only valid Posix file names. Use only Ascii letters, digits, `.',
32# `-' and `_'. Do not exceed 14 characters or start with `-'.
33# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
34# Include at least one location per time zone rule set per country.
35# One such location is enough.
36# If all the clocks in a country's region have agreed since 1970,
37# don't bother to include more than one location
38# even if subregions' clocks disagreed before 1970.
39# Otherwise these tables would become annoyingly large.
40# If a name is ambiguous, use a less ambiguous alternative;
41# e.g. many cities are named San Jose and Georgetown, so
42# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
43# Keep locations compact. Use cities or small islands, not countries
44# or regions, so that any future time zone changes do not split
45# locations into different time zones. E.g. prefer `Paris'
46# to `France', since France has had multiple time zones.
47# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
48# prefer `Athens' to the true name (which uses Greek letters).
49# The Posix file name restrictions encourage this rule.
50# Use the most populous among locations in a country's time zone,
51# e.g. prefer `Shanghai' to `Beijing'. Among locations with
52# similar populations, pick the best-known location,
53# e.g. prefer `Rome' to `Milan'.
54# Use the singular form, e.g. prefer `Canary' to `Canaries'.
55# Omit common suffixes like `_Islands' and `_City', unless that
56# would lead to ambiguity. E.g. prefer `Cayman' to
57# `Cayman_Islands' and `Guatemala' to `Guatemala_City',
58# but prefer `Mexico_City' to `Mexico' because the country
59# of Mexico has several time zones.
60# Use `_' to represent a space.
61# Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
62# to `St._Helena'.
63#
64# We typically use traditional English time zone abbreviations,
65# and assume that applications translate them to other languages
66# as part of the normal localization process.
67#
68# I made up the following time zone abbreviations; corrections are welcome!
69# LMT Local Mean Time
70# -2:00 CVT Cape Verde Time (no longer used)
71# -1:00 AAT Atlantic Africa Time
72# 0:00 WAT West Africa Time
73# 1:00 CAT Central Africa Time
74# 2:00 SAT South Africa Time
75# 3:00 EAT East Africa Time
76# 4:00 SMT Seychelles and Mascarene Time
77# The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
78# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.

7# From Paul Eggert <eggert@twinsun.com> (November 18, 1993):
8#
9# A good source for time zone historical data outside the U.S. is
10# Thomas G. Shanks, The International Atlas (3rd edition),
11# San Diego: ACS Publications, Inc. (1991).
12# Except where otherwise noted, it is the source for the data below.
13#
14# Another source occasionally used is Edward W. Whitman, World Time Differences,
15# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
16# I found in the UCLA library.
17#
18# A reliable and entertaining source about time zones is
19# Derek Howse, Greenwich time and the discovery of the longitude,
20# Oxford University Press (1980).
21#
22# I added so many Zone names that the old, mostly flat name space was unwieldy.
23# So I renamed the Zones to have the form AREA/LOCATION, where
24# AREA is the name of a continent or ocean, and
25# LOCATION is the name of a specific location within that region.
26# For example, the old zone name `Egypt' is now `Africa/Cairo'.
27#
28# Here are the general rules I used for choosing location names,
29# in decreasing order of importance:
30#
31# Use only valid Posix file names. Use only Ascii letters, digits, `.',
32# `-' and `_'. Do not exceed 14 characters or start with `-'.
33# E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
34# Include at least one location per time zone rule set per country.
35# One such location is enough.
36# If all the clocks in a country's region have agreed since 1970,
37# don't bother to include more than one location
38# even if subregions' clocks disagreed before 1970.
39# Otherwise these tables would become annoyingly large.
40# If a name is ambiguous, use a less ambiguous alternative;
41# e.g. many cities are named San Jose and Georgetown, so
42# prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
43# Keep locations compact. Use cities or small islands, not countries
44# or regions, so that any future time zone changes do not split
45# locations into different time zones. E.g. prefer `Paris'
46# to `France', since France has had multiple time zones.
47# Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
48# prefer `Athens' to the true name (which uses Greek letters).
49# The Posix file name restrictions encourage this rule.
50# Use the most populous among locations in a country's time zone,
51# e.g. prefer `Shanghai' to `Beijing'. Among locations with
52# similar populations, pick the best-known location,
53# e.g. prefer `Rome' to `Milan'.
54# Use the singular form, e.g. prefer `Canary' to `Canaries'.
55# Omit common suffixes like `_Islands' and `_City', unless that
56# would lead to ambiguity. E.g. prefer `Cayman' to
57# `Cayman_Islands' and `Guatemala' to `Guatemala_City',
58# but prefer `Mexico_City' to `Mexico' because the country
59# of Mexico has several time zones.
60# Use `_' to represent a space.
61# Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
62# to `St._Helena'.
63#
64# We typically use traditional English time zone abbreviations,
65# and assume that applications translate them to other languages
66# as part of the normal localization process.
67#
68# I made up the following time zone abbreviations; corrections are welcome!
69# LMT Local Mean Time
70# -2:00 CVT Cape Verde Time (no longer used)
71# -1:00 AAT Atlantic Africa Time
72# 0:00 WAT West Africa Time
73# 1:00 CAT Central Africa Time
74# 2:00 SAT South Africa Time
75# 3:00 EAT East Africa Time
76# 4:00 SMT Seychelles and Mascarene Time
77# The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
78# BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.
