Make deals with the timestamps of files, and - I assume - needs to
have some awareness of the possibility that timestamp resolution
issues will give just-touched files a timestamp which is in the past,
and perhaps a timestamp which is _before_ the time which was current
immediately prior to the filesystem operation.

Glibc systems sometimes also support FAT filesystems.
