[PATCH 1/2] Added "Z" as an alias for the timezone "UTC"

[Marcus Comstedt <marcus@mc.pp.se>]

The name "Z" for the UTC timezone is required to properly parse
ISO 8601 times.  Added it to the list of recignozed timezones.

Also, fixed the bug that timezone names shorter than 3 characters
can never be matched by match_alpha().  Prior to the introduction
of the "Z" zone, this affected the timezone "NT" (Nome).
