5 # tz@elsie.nci.nih.gov for general use in the future).
7 # From Paul Eggert <eggert@twinsun.com> (1996-11-22):
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).
13 # Gwillim Law <LAW@encmail.encompass.com> writes that a good source
14 # for recent time zone data is the International Air Transport
15 # Association's Standard Schedules Information Manual (IATA SSIM),
16 # published semiannually. Law sent in several helpful summaries
17 # of the IATA's data after 1990.
19 # Except where otherwise noted, Shanks is the source for entries through 1990,
20 # and IATA SSIM is the source for entries after 1990.
22 # Another source occasionally used is Edward W. Whitman, World Time Differences,
23 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24 # I found in the UCLA library.
26 # A reliable and entertaining source about time zones is
27 # Derek Howse, Greenwich time and the discovery of the longitude,
28 # Oxford University Press (1980).
30 # I added so many Zone names that the old, mostly flat name space was unwieldy.
31 # So I renamed the Zones to have the form AREA/LOCATION, where
32 # AREA is the name of a continent or ocean, and
33 # LOCATION is the name of a specific location within that region.
34 # For example, the old zone name `Egypt' is now `Africa/Cairo'.
36 # Here are the general rules I used for choosing location names,
37 # in decreasing order of importance:
39 # Use only valid Posix file names. Use only Ascii letters, digits, `.',
40 # `-' and `_'. Do not exceed 14 characters or start with `-'.
41 # E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
42 # Include at least one location per time zone rule set per country.
43 # One such location is enough.
44 # If all the clocks in a country's region have agreed since 1970,
45 # don't bother to include more than one location
46 # even if subregions' clocks disagreed before 1970.
47 # Otherwise these tables would become annoyingly large.
48 # If a name is ambiguous, use a less ambiguous alternative;
49 # e.g. many cities are named San Jose and Georgetown, so
50 # prefer `Costa_Rica' to `San_Jose' and `Guyana' to `Georgetown'.
51 # Keep locations compact. Use cities or small islands, not countries
52 # or regions, so that any future time zone changes do not split
53 # locations into different time zones. E.g. prefer `Paris'
54 # to `France', since France has had multiple time zones.
55 # Use traditional English spelling, e.g. prefer `Rome' to `Roma', and
56 # prefer `Athens' to the true name (which uses Greek letters).
57 # The Posix file name restrictions encourage this rule.
58 # Use the most populous among locations in a country's time zone,
59 # e.g. prefer `Shanghai' to `Beijing'. Among locations with
60 # similar populations, pick the best-known location,
61 # e.g. prefer `Rome' to `Milan'.
62 # Use the singular form, e.g. prefer `Canary' to `Canaries'.
63 # Omit common suffixes like `_Islands' and `_City', unless that
64 # would lead to ambiguity. E.g. prefer `Cayman' to
65 # `Cayman_Islands' and `Guatemala' to `Guatemala_City',
66 # but prefer `Mexico_City' to `Mexico' because the country
67 # of Mexico has several time zones.
68 # Use `_' to represent a space.
69 # Omit `.' from abbreviations in names, e.g. prefer `St_Helena'
72 # For time zone abbreviations like `EST' I used the following rules,
73 # in decreasing order of importance:
75 # Use abbreviations that consist of 3 or more upper-case Ascii letters,
76 # except use "___" for locations while uninhabited.
77 # Posix.1 requires at least 3 characters, and the restriction to
78 # upper-case Ascii letters follows most traditions.
79 # Previous editions of this database also used characters like
80 # ' ' and '?', but these characters have a special meaning to
81 # the shell and cause commands like
83 # to have unexpected effects. In theory, the character set could
84 # be !%./@A-Z^_a-z{}, but these tables use only upper-case
85 # Ascii letters (and "___").
86 # Use abbreviations that are in common use among English-speakers,
87 # e.g. `EST' for Eastern Standard Time in North America.
88 # We assume that applications translate them to other languages
89 # as part of the normal localization process; for example,
90 # a French application might translate `EST' to `HNE'.
91 # For zones whose times are taken from a city's longitude, use the
92 # traditional xMT notation, e.g. `PMT' for Paris Mean Time.
93 # The only name like this in current use is `GMT'.
94 # If there is no common English abbreviation, abbreviate the English
95 # translation of the usual phrase used by native speakers.
96 # If this is not available or is a phrase mentioning the country
97 # (e.g. ``Cape Verde Time''), then:
99 # When a country has a single or principal time zone region,
100 # append `T' to the country's ISO code, e.g. `CVT' for
101 # Cape Verde Time. For summer time append `ST';
102 # for double summer time append `DST'; etc.
103 # When a country has multiple time zones, take the first three
104 # letters of an English place name identifying each zone
105 # and then append `T', `ST', etc. as before;
106 # e.g. `MOSST' for MOScow Summer Time.
109 # For Africa I invented the following time zone abbreviations.
110 # LMT Local Mean Time
111 # -1:00 AAT Atlantic Africa Time (no longer used)
112 # 0:00 WAT West Africa Time
113 # 1:00 CAT Central Africa Time
114 # 2:00 SAT South Africa Time
115 # 3:00 EAT East Africa Time
116 # The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
117 # BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.
