3 # This data is by no means authoritative; if you think you know better,
4 # go ahead and edit the file (and please send any changes to
5 # tz@elsie.nci.nih.gov for general use in the future).
7 # From Paul Eggert <eggert@twinsun.com> (1996-09-03):
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 # For time zone abbreviations like `EST' I used the following rules,
65 # in decreasing order of importance:
66 #
67 # Use abbreviations that consist of 3 or more upper-case Ascii letters,
68 # except use "___" for locations while uninhabited.
69 # Posix.1 requires at least 3 characters, and the restriction to
70 # upper-case Ascii letters follows most traditions.
71 # Previous editions of this database also used characters like
72 # ' ' and '?', but these characters have a special meaning to
73 # the shell and cause commands like
74 # set `date`
75 # to have unexpected effects. In theory, the character set could
76 # be !%./@A-Z^_a-z{}, but these tables use only upper-case
77 # Ascii letters (and "___").
78 # Use abbreviations that are in common use among English-speakers,
79 # e.g. `EST' for Eastern Standard Time in North America.
80 # We assume that applications translate them to other languages
81 # as part of the normal localization process; for example,
82 # a French application might translate `EST' to `HNE'.
83 # For zones whose times are taken from a city's longitude, use the
84 # traditional xMT notation, e.g. `PMT' for Paris Mean Time.
85 # The only name like this in current use is `GMT'.
86 # If there is no common English abbreviation, abbreviate the English
87 # translation of the usual phrase used by native speakers.
88 # If this is not available or is a phrase mentioning the country
89 # (e.g. ``Cape Verde Time''), then:
90 #
91 # When a country has a single or principal time zone region,
92 # append `T' to the country's ISO code, e.g. `CVT' for
93 # Cape Verde Time. For summer time append `ST';
94 # for double summer time append `DST'; etc.
95 # When a country has multiple time zones, take the first three
96 # letters of an English place name identifying each zone
97 # and then append `T', `ST', etc. as before;
98 # e.g. `MOSST' for MOScow Summer Time.
99 #
100 #
101 # For Africa I invented the following time zone abbreviations.
102 # LMT Local Mean Time
103 # -1:00 AAT Atlantic Africa Time (no longer used)
104 # 0:00 WAT West Africa Time
105 # 1:00 CAT Central Africa Time
106 # 2:00 SAT South Africa Time
107 # 3:00 EAT East Africa Time
108 # The final `T' is replaced by `ST' for summer time, e.g. `SAST'.
109 # BEAT is British East Africa Time, which was 2:30 before 1948 and 2:45 after.
