File timestamps and timezones

Last week I was in Perth (timezone GMT+8, no daylight saving). I created
some files on a WinXP Pro workstation there which I copied across our
network to my normal WinXP Pro workstation in Canberra (timezone GMT+8,
daylight saving presently no, so effectively GMT+11), and I also copied the
files to a USB memory key formatted with the FAT32 file system.

This week I'm back in Canberra and plug the memory key into my workstation.
When I compare the timestamps of the files on the memory key with the same
files that were copied across the network, the files that were copied across
the network show up as being three hours more recent. Why is this so? Must
be something to do with the three hour time difference between the two
workstations, but my understanding is that the NTFS file system stores file
times internally in GMT. How does it store them on FAT32?
