This will never happen if you're running NTP.  NTP does gradual 
adjustments to the clock rate to ensure that the system clock is always 
monotonically increasing.

It can happen if you're running some kind of time sync service other 
than NTP.  Why anybody would want to do such a thing is beyond me.
