I agree in part -- but the fact the the file exists on a current
filesystem goes to show that it is a problem which exists today. Other
tools like touch and ls clearly handle these timestamps with no problem.

I can obviously work around the problem by resetting the bad timestamps,
but I thought i'd raise it as an issue since it may be causing to rsync
to scan files unnecessarily in some cases.

Files do occasionally get broken timestamps for all kinds of reasons.
