update-version: Use UTC with version timestamps.

If we don't use same timezone, we can get funny times,
because we are on different timezones.

For example, I could commit something at 16:00, then
ProgVal/nyuszika7h/skizzhg/Banton could commit some-
thing and timestamp would only show that it happened
at the same time on different timezone.

Timestamps using specific timezone could also make
reading of version numbers easier.
