Um, so how does the camera show the timestamp of file? UTC seems to be
hack for changing FAT for Linux. Arbitrary value is more useful and
correct option, I think.

It will be specified the timezone of FAT on one disk. So, the timestamp
is right for specified timezone on Windows always, on Linux should be
always right. If you want to write, of course, you can specify UTC by it
to write timestamp as UTC to FAT.

No?
