  2. # This file is in the public domain, so clarified as of
  3. # 2009-05-17 by Arthur David Olson.
  4. # This data is by no means authoritative; if you think you know better,
  5. # go ahead and edit the file (and please send any changes to
  6. # tz@iana.org for general use in the future).
  7. # From Paul Eggert (2006-03-22):
  8. #
  9. # A good source for time zone historical data outside the U.S. is
  10. # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
  11. # San Diego: ACS Publications, Inc. (2003).
  12. #
  13. # Gwillim Law 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.
  18. #
  19. # Except where otherwise noted, Shanks & Pottenger is the source for
  20. # entries through 1990, and IATA SSIM is the source for entries afterwards.
  21. #
  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.
  25. #
  26. # A reliable and entertaining source about time zones is
  27. # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
  28. #
  29. # Previous editions of this database used WAT, CAT, SAT, and EAT
  30. # for +0:00 through +3:00, respectively,
  31. # but Mark R V Murray reports that
  32. # `SAST' is the official abbreviation for +2:00 in the country of South Africa,
  33. # `CAT' is commonly used for +2:00 in countries north of South Africa, and
  34. # `WAT' is probably the best name for +1:00, as the common phrase for
  35. # the area that includes Nigeria is ``West Africa''.
  36. # He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
  37. #
  38. # To make things confusing, `WAT' seems to have been used for -1:00 long ago;
  39. # I'd guess that this was because people needed _some_ name for -1:00,
  40. # and at the time, far west Africa was the only major land area in -1:00.
  41. # This usage is now obsolete, as the last use of -1:00 on the African
  42. # mainland seems to have been 1976 in Western Sahara.
  43. #
  44. # To summarize, the following abbreviations seem to have some currency:
  45. # -1:00 WAT West Africa Time (no longer used)
  46. # 0:00 GMT Greenwich Mean Time
  47. # 2:00 CAT Central Africa Time
  48. # 2:00 SAST South Africa Standard Time
  49. # and Murray suggests the following abbreviation:
  50. # 1:00 WAT West Africa Time
  51. # I realize that this leads to `WAT' being used for both -1:00 and 1:00
  52. # for times before 1976, but this is the best I can think of
  53. # until we get more information.
  54. #
  55. # I invented the following abbreviations; corrections are welcome!
  56. # 2:00 WAST West Africa Summer Time
  57. # 2:30 BEAT British East Africa Time (no longer used)
  58. # 2:45 BEAUT British East Africa Unified Time (no longer used)
  59. # 3:00 CAST Central Africa Summer Time (no longer used)
  60. # 3:00 SAST South Africa Summer Time (no longer used)
  61. # 3:00 EAT East Africa Time
  62. # 4:00 EAST East Africa Summer Time (no longer used)

  224. # From Abdelrahman Hassan (2007-09-06):
  225. # Due to the Hijri (lunar Islamic calendar) year being 11 days shorter
  226. # than the year of the Gregorian calendar, Ramadan shifts earlier each
  227. # year. This year it will be observed September 13 (September is quite
  228. # hot in Egypt), and the idea is to make fasting easier for workers by
  229. # shifting business hours one hour out of daytime heat. Consequently,
  230. # unless discontinued, next DST may end Thursday 28 August 2008.
  231. # From Paul Eggert (2007-08-17):
  232. # For lack of better info, assume the new rule is last Thursday in August.

  470. # (in French), Mauritius will start and end their DST a few days earlier
  471. # than previously announced (2008-11-01 to 2009-03-31). The new start
  472. # date is 2008-10-26 at 02:00 and the new end date is 2009-03-27 (no time
  473. # given, but it is probably at either 2 or 3 wall clock time).
  474. #
  475. # A little strange though, since the article says that they moved the date
  476. # to align itself with Europe and USA which also change time on that date,
  477. # but that means they have not paid attention to what happened in
  478. # USA/Canada last year (DST ends first Sunday in November). I also wonder

  480. # changes two days later.
