Hm. Just a mumbling from the peanut gallery: isn't the timezone a property
of the timestamp itself?

Specifying the timezone for the whole file is progress, but imagine the
following scenario: I have a big file which is more or less a diary of
things which happened, with lots of timestamps thrown in (also LOGBOOK
entries).

If I move through timezones, only some of the timestamps are "elsewhere".

Switching "the whole file" to reflect the "current" timezone feels somehow
wrong to me (which timezone a specific timestamp "happened" in has also
some documentary value, after all).

To keep things unambiguous, more than just the timezone must be kept.
The current time offset is necessary to actually reconstruct the time
(DST and such things).

Of course, convincing Org to extend the timestamp format and regexps
might be a tough call :-)
