/* This table maps Windows timezone keynames and countries per ISO 3166-1 to
POSIX-compatible timezone IDs. The information is taken from
http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/zone_tzid.html
The mapping from unicode.org is just a bit incomplete. It doesn't contain
a few timezones available on Windows XP, namely:
Armenian Standard Time
Mexico Standard Time
Mexico Standard Time 2
as well as the still (Windows 7) available
Mid-Atlantic Standard Time
It also doesn't contain some of the deprecated country codes used in older
OSes, namely:
SP (Serbian, proposed) used in XP
CS (Serbian and Montenegro, dissolved, now RS and ME) used in Vista
While these are apparently old, they are required here to get a complete
mapping on all supported OSes. */

Usage: tzset [OPTION]
Print POSIX-compatible timezone ID from current Windows timezone setting
Options:
-h, --help output usage information and exit.
-V, --version output version information and exit.
Use tzset to set your TZ variable. In POSIX-compatible shells like bash,
dash, mksh, or zsh:
export TZ=$(tzset)
In csh-compatible shells like tcsh:
setenv TZ `tzset`
</screen>
<para>The <command>tzset</command> tool reads the current timezone from Windows
and generates a POSIX-compatible timezone information for the TZ environment
variable from that information. That's all there is to it. For the way how
to use it, see the above usage information.</para>
