Nope. As soon as you import into your computer, it will be offset by 
(-1)(UTCOffset) on your computer. So, that's why in the original eMail I 
said my workaround was to run f-spot itself in the UTC timezone.

Neither of those will work. When I felt the need to unmangle the 
timezone alterations by f-spot, I deleted the f-spot database, wrote a 
shell script that used exiftime to copy one of the original dates back 
to where it belongs, and then reimported into f-spot with TZ=UTC.

Now you see why f-spot should not be handling timezones? There are a 
million scenarios to handle. Without timezone handling, f-spot could 
just show the date as it appears in the photo and save a lot of headache.
