SYNOPSIS

DESCRIPTION

18       This module provides methods for determining the local time zone on a
19       Unix platform.

HOW THE TIME ZONE IS DETERMINED

22       This class tries the following methods of determining the local time
23       zone:
24
25       ·   $ENV{TZ}
26
27           It checks $ENV{TZ} for a valid time zone name.
28
29       ·   /etc/localtime
30
31           If this file is a symlink to an Olson database time zone file
32           (usually in /usr/share/zoneinfo) then it uses the target file's
33           path name to determine the time zone name. For example, if the path
34           is /usr/share/zoneinfo/America/Chicago, the time zone is
35           "America/Chicago".
36
37           Some systems just copy the relevant file to /etc/localtime instead
38           of making a symlink.  In this case, we look in /usr/share/zoneinfo
39           for a file that has the same size and content as /etc/localtime to
40           determine the local time zone.
41
42       ·   /etc/timezone
43
44           If this file exists, it is read and its contents are used as a time
45           zone name.
46
47       ·   /etc/TIMEZONE
48
49           If this file exists, it is opened and we look for a line starting
50           like "TZ = ...". If this is found, it should indicate a time zone
51           name.
52
53       ·   /etc/sysconfig/clock
54
55           If this file exists, it is opened and we look for a line starting
56           like "TIMEZONE = ..." or "ZONE = ...". If this is found, it should
57           indicate a time zone name.
58
59       ·   /etc/default/init
60
61           If this file exists, it is opened and we look for a line starting
62           like "TZ=...". If this is found, it should indicate a time zone
63           name.
