But f-spot probably shouldn't change the local times in the photos. When
you reimport f-spot photos (for whatever reason), the dates get shifted

However, it's possible to abuse the GPSTimeStamp EXIF tag to store a UTC
time, according to:

f-spot could check for that tag on import and use it if present, or
create it (based on the computer's timezone) if not. Ugly, no? :)
