/* 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`
|

|

|

<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>
