F-Spot stores the time today as UTC time, and everything internally is
done in UTC time, which you as a user do not see, nor should know about.
So, from that perspective, there would be no difference.
Only from the storing of the time in the Embedded XMP data, as well as
actually getting the time correct in the first place :)

So, to recapitulate:

1) From user, there would be no difference, all photos would be
displayed in local time. (Not quite sure how the sorting would affect
this, if you have photos from two timezones though!) Comments?

2) The embedded XMP information would show the accurate local time the
photo was taken, with timezone.

3) The EXIF would be the local time when the photo was taken, without
timezone.

4) The time would be stored as UTC in the SQlite database.

5) The import gui would have to be done as simple as possible.
Preferably with as little "scary" impact on the user as possible.
Perhaps an Advance import button, where you can specify the two extra
timezones?
