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

VERSION
       version 1.70

SYNOPSIS
         my $tz = DateTime::TimeZone->new( name => 'local' );

         my $tz = DateTime::TimeZone::Local->TimeZone();

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

HOW THE TIME ZONE IS DETERMINED
       This class tries the following methods of determining the local time zone:

       o   $ENV{TZ}

           It checks $ENV{TZ} for a valid time zone name.

       o   /etc/localtime

           If this file is a symlink to an Olson database time zone file (usually in
           /usr/share/zoneinfo) then it uses the target file's path name to determine the time
           zone name. For example, if the path is /usr/share/zoneinfo/America/Chicago, the time
           zone is "America/Chicago".

           Some systems just copy the relevant file to /etc/localtime instead of making a
           symlink.  In this case, we look in /usr/share/zoneinfo for a file that has the same
           size and content as /etc/localtime to determine the local time zone.

       o   /etc/timezone

           If this file exists, it is read and its contents are used as a time zone name.

       o   /etc/TIMEZONE

           If this file exists, it is opened and we look for a line starting like "TZ = ...". If
           this is found, it should indicate a time zone name.

       o   /etc/sysconfig/clock

           If this file exists, it is opened and we look for a line starting like "TIMEZONE =
           ..." or "ZONE = ...". If this is found, it should indicate a time zone name.

       o   /etc/default/init

           If this file exists, it is opened and we look for a line starting like "TZ=...". If
           this is found, it should indicate a time zone name.
