  6. # people in areas not otherwise covered by the tz files could "zic -l"
  7. # to a time zone that was right for their area. These days, the
  8. # tz files cover almost all the inhabited world, and the only practical
  9. # need now for the entries that are not on UTC are for ships at sea
  10. # that cannot use POSIX TZ settings.

  14. # The following link uses older naming conventions,
  15. # but it belongs here, not in the file `backward',
  16. # as functions like gmtime load the "GMT" file to handle leap seconds properly.
  17. # We want this to work even on installations that omit the other older names.

  25. # We use POSIX-style signs in the Zone names and the output abbreviations,
  26. # even though this is the opposite of what many people expect.
  27. # POSIX has positive signs west of Greenwich, but many people expect
  28. # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses
  29. # the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
  30. # (i.e. west of Greenwich) even though many people would expect it to
  31. # mean 4 hours ahead of UTC (i.e. east of Greenwich).
  32. #
  33. # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for
  34. # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
  35. # ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected
  36. # offset is kept within the angle bracket (and is used for display)
  37. # while the POSIX sign is kept outside the angle bracket (and is used
  38. # for calculation).
  39. #
  40. # Do not use a TZ setting like TZ='GMT+4', which is four hours behind
  41. # GMT but uses the completely misleading abbreviation "GMT".
  42. # Earlier incarnations of this package were not POSIX-compliant,

  45. # We did not want things to change quietly if someone accustomed to the old
  46. # way does a
  47. # zic -l GMT-12
  48. # so we moved the names into the Etc subdirectory.
