But the above `experiment' has nothing to do with vfat partitions: both systems
are linux ext3. What I don't understand is how can a user from the 2nd system
know that the file has been created at 14:43 UTC and not at 14:43 of its local
time, since all files of his filesystem are displayed in the local time.
