It is fairly simple to compare the timestamps in the repomd.xml files.
 If the timestamps are older than the master, then the mirror is
out-of-date.  This doesn't help with mirrors which are in the middle
of syncing or had a failure.  Mirrors could use the rsync
--delay-updates option to make the updates more atomic.
