Jan 1 1980 is the start of the DOS epoch. Your system is getting '0'
as the modification time on the root directory of the mounts.

Now you are getting the modification time of the directory that was
underneath the mounts, that is, the actual directory node in /mnt, and
not the root of the filesystem mounted at /mnt/win2k*.

MSDOS FAT filesystems do not have owners or permissions to set.
