[PATCH] cg-Xlib: make showdate show timezone

[Dan Holmsand <holmsand@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 242 bytes --]

This makes timezones show up again in showdate's default
format. Hopefully, this also makes showdate a little more
portable.

It also speeds things up a little, by avoiding an extra fork.
