NAME

6       DateTime::TimeZone::Local::Unix - Determine the local system's time
7       zone on Unix

SYNOPSIS

10         my $tz = DateTime::TimeZone->new( name => 'local' );
11
12         my $tz = DateTime::TimeZone::Local->TimeZone();

DESCRIPTION

15       This module provides methods for determining the local time zone on a
16       Unix platform.
17

HOW THE TIME ZONE IS DETERMINED

19       This class tries the following methods of determining the local time
20       zone:
21
22       ·   $ENV{TZ}
23
24           It checks $ENV{TZ} for a valid time zone name.
25
26       ·   /etc/localtime
27
28           If this file is a symlink to an Olson database time zone file
29           (usually in /usr/share/zoneinfo) then it uses the target file's
30           path name to determine the time zone name. For example, if the path
31           is /usr/share/zoneinfo/America/Chicago, the time zone is
32           "America/Chicago".
33
34           Some systems just copy the relevant file to /etc/localtime instead
35           of making a symlink.  In this case, we look in /usr/share/zoneinfo
36           for a file that has the same size and content as /etc/localtime to
37           determine the local time zone.
38
39       ·   /etc/timezone
40
41           If this file exists, it is read and its contents are used as a time
42           zone name.
43
44       ·   /etc/TIMEZONE
45
46           If this file exists, it is opened and we look for a line starting
47           like "TZ = ...". If this is found, it should indicate a time zone
48           name.
49
50       ·   /etc/sysconfig/clock
51
52           If this file exists, it is opened and we look for a line starting
53           like "TIMEZONE = ..." or "ZONE = ...". If this is found, it should
54           indicate a time zone name.
55
56       ·   /etc/default/init
57
58           If this file exists, it is opened and we look for a line starting
59           like "TZ=...". If this is found, it should indicate a time zone
60           name.
