  1. # Zones that go back beyond the scope of the tz database
  2. # This file is in the public domain.
  3. # This file is by no means authoritative; if you think you know
  4. # better, go ahead and edit it (and please send any changes to
  5. # tz@iana.org for general use in the future). For more, please see
  6. # the file CONTRIBUTING in the tz distribution.
  7. # From Paul Eggert (2014-10-31):
  8. # This file contains data outside the normal scope of the tz database,
  9. # in that its zones do not differ from normal tz zones after 1970.
  10. # Links in this file point to zones in this file, superseding links in
  11. # the file 'backward'.
  12. # Although zones in this file may be of some use for analyzing
  13. # pre-1970 time stamps, they are less reliable, cover only a tiny
  14. # sliver of the pre-1970 era, and cannot feasibly be improved to cover
  15. # most of the era. Because the zones are out of normal scope for the
  16. # database, less effort is put into maintaining this file. Many of
  17. # the zones were formerly in other source files, but were removed or
  18. # replaced by links as their data entries were questionable and/or they
  19. # differed from other zones only in pre-1970 time stamps.
  20. # Unless otherwise specified, the source for data through 1990 is:
  21. # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
  22. # San Diego: ACS Publications, Inc. (2003).
  23. # Unfortunately this book contains many errors and cites no sources.
  24. # This file is not intended to be compiled standalone, as it
  25. # assumes rules from other files. In the tz distribution, use
  26. # 'make PACKRATDATA=backzone zones' to compile and install this file.
  27. # Zones are sorted by zone name. Each zone is preceded by the
  28. # name of the country that the zone is in, along with any other
  29. # commentary and rules associated with the entry.
  30. #
  31. # As explained in the zic man page, the zone columns are:
  32. # Zone NAME GMTOFF RULES FORMAT [UNTIL]
  33. # Ethiopia
  34. # From Paul Eggert (2014-07-31):
  35. # Like the Swahili of Kenya and Tanzania, many Ethiopians keep a
  36. # 12-hour clock starting at our 06:00, so their "8 o'clock" is our
  37. # 02:00 or 14:00. Keep this in mind when you ask the time in Amharic.
  38. #
  39. # Shanks & Pottenger write that Ethiopia had six narrowly-spaced time
  40. # zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in
  41. # 1890, and that they switched to 3:00 on 1936-05-05. Perhaps 38E50
  42. # was for Adis Dera. Quite likely the Shanks data entries are wrong
  43. # anyway.
