NAME

SYNOPSIS

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           It checks $ENV{TZ} for a valid time zone name.
24
25       * /etc/localtime
26           If this file is a symlink to an Olson database time zone file (usu‐
27           ally in /usr/share/zoneinfo) then it uses the target file's path to
28           determine the time zone name.
29
30           If this file is a copy of a zoneinfo file, it looks for a file that
31           matches this file in /usr/share/zoneinfo. If it finds one, it uses
32           that file's path to determine the time zone name.
33
34       * /etc/timezone
35           If this file exists, it is read and its contents are used as a time
36           zone name.
37
38       * /etc/TIMEZONE
39           If this file exists, it is opened and we look for a line starting
40           like "TZ = ...". If this is found, it should indicate a time zone
41           name.
42
43       * /etc/sysconfig/clock
44           If this file exists, it is opened and we look for a line starting
45           like "TIMEZONE = ..." or "ZONE = ...". If this is found, it should
46           indicate a time zone name.
47
48       * /etc/default/init
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.
