Unless I am missing something, I do not think this would do much. Here 
is an example I just tried:

I took a photo taken at 00:10 and imported into f-spot. The time became 
05:10.

If my camera's time had been set to UTC, the photo time would have been 
05:10 to start with. Upon importing, the time would be changed to 10:10.

I think that the only thing that would modify this behaviour is if 
f-spot was made to think I am in the UTC timezone. In theory, it would 
offset the photos by 0 hours then.

Indeed, a quick test launching "TZ=UTC f-spot" avoids the time offset.
