3 The /usr/share/lib/zoneinfo/src directory contains zoneinfo timezone source
4 files. These source files have been compiled using zic(1M) to create
5 the zoneinfo data files in /usr/share/lib/zoneinfo. The zic command can be
6 used with the zoneinfo source files to create additional data files.
7
8 The zoneinfo files track the Olson public source provided at
9 ftp://elsie.nci.nih.gov/pub/, therefore zoneinfo files may be added and
10 removed as the Solaris source is updated. The current Solaris release of
11 the zoneinfo files is based on tzdata2010k.tar.gz.
12
13 The /usr/share/lib/zoneinfo/GMT[+-]* timezones listed below have been
14 removed 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
17 timezone are reversed from the signs of the /usr/share/lib/zoneinfo/GMT[+-]*
18 files.
19
20 For example, replace TZ=:GMT+1, with TZ="<GMT-1>-1". (The colon (:) is
21 significant. Without the colon, for example TZ=GMT+1, an unquoted timezone
22 is used; unquoted timezones are not affected by the removal of the zoneinfo
23 timezone files listed below.)
24
25 The 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

53 As zoneinfo timezones are updated, the savings/daylight transition rules
54 and timezone name abbreviations may change. This can affect how
55 the times are calculated in the local timezone. Therefore the interpretation
56 of a time_t value can vary amongst Solaris releases that use different
57 versions of the zoneinfo timezones.
58
59 The zoneinfo timezone data files do not transition past
60 Tue Jan 19 03:14:07 2038 GMT. Therefore for 64-bit applications using
61 zoneinfo timezones, calculations beyond this date may not use the correct
62 offset from standard time, and could return incorrect values. This affects
63 64-bit versions of interfaces such as ascftime(3C), cftime(3C), ctime(3C),
64 getdate(3C), ftime(3C), mktime(3C), and localtime(3C).

67 ctime(3C), and mktime(3C) man pages.
