As long as the user doesn't see it, then the way F-Spot works
internally doesn't matter to him. However, other XMP-compliant tools
may give them strange results, if they display in UTC and the user was

Sounds good that all the photos would be displayed in local time. And
they will be sorted in the order that they were shot- very logical
asuming that is the case.
