These source files have been compiled using zic(1M) to create 5the zoneinfo data files in /usr/share/lib/zoneinfo. The zic command can be 6used with the zoneinfo source files to create additional data files. 7 8The zoneinfo files track the Olson public source provided at 9ftp://elsie.nci.nih.gov/pub/, therefore zoneinfo files may be added and 10removed as the Solaris source is updated. The current Solaris release of 11the zoneinfo files is based on tzdata2010k.tar.gz. 12 13The /usr/share/lib/zoneinfo/GMT[+-]* timezones listed below have been 14removed from the release. Replace usage of the 15/usr/share/lib/zoneinfo/GMT[+-]* files with the equivalent quoted timezone 16(see environ(5)). Note the signs of the offsets of the equivalent quoted 17timezone are reversed from the signs of the /usr/share/lib/zoneinfo/GMT[+-]* 18files. 19 20For example, replace TZ=:GMT+1, with TZ="<GMT-1>-1". (The colon (:) is 21significant. Without the colon, for example TZ=GMT+1, an unquoted timezone 22is used; unquoted timezones are not affected by the removal of the zoneinfo 23timezone files listed below.) 24 25The following files have been removed from the release: 26 27/usr/share/lib/zoneinfo/GMT-12 28/usr/share/lib/zoneinfo/GMT-11 29/usr/share/lib/zoneinfo/GMT-10 30/usr/share/lib/zoneinfo/GMT-9 31/usr/share/lib/zoneinfo/GMT-8 32/usr/share/lib/zoneinfo/GMT-7 33/usr/share/lib/zoneinfo/GMT-6 34/usr/share/lib/zoneinfo/GMT-5 35/usr/share/lib/zoneinfo/GMT-4 36/usr/share/lib/zoneinfo/GMT-3 37/usr/share/lib/zoneinfo/GMT-2 38/usr/share/lib/zoneinfo/GMT-1 39/usr/share/lib/zoneinfo/GMT+1 40/usr/share/lib/zoneinfo/GMT+2 41/usr/share/lib/zoneinfo/GMT+3 42/usr/share/lib/zoneinfo/GMT+4 43/usr/share/lib/zoneinfo/GMT+5 44/usr/share/lib/zoneinfo/GMT+6 45/usr/share/lib/zoneinfo/GMT+7 46/usr/share/lib/zoneinfo/GMT+8 47/usr/share/lib/zoneinfo/GMT+9 48/usr/share/lib/zoneinfo/GMT+10 49/usr/share/lib/zoneinfo/GMT+11 50/usr/share/lib/zoneinfo/GMT+12 51/usr/share/lib/zoneinfo/GMT+13 52 53As zoneinfo timezones are updated, the savings/daylight transition rules 54and timezone name abbreviations may change. This can affect how 55the times are calculated in the local timezone. Therefore the interpretation 56of a time_t value can vary amongst Solaris releases that use different 57versions of the zoneinfo timezones. 58 59The zoneinfo timezone data files do not transition past 60Tue Jan 19 03:14:07 2038 GMT. Therefore for 64-bit applications using 61zoneinfo timezones, calculations beyond this date may not use the correct 62offset from standard time, and could return incorrect values. This affects 6364-bit versions of interfaces such as ascftime(3C), cftime(3C), ctime(3C), 64getdate(3C), ftime(3C), mktime(3C), and localtime(3C). 65 66For more information see zic(1M), zdump(1M), environ(5), TIMEZONE(4), 67ctime(3C), and mktime(3C) man pages. 68
