I have seen something similiar.  One of our Sun Sparc workstations is
used a lot for Graphics.  During the night, xntpd gets the time synched
pretty close to our time servers.  But during the day, it gets out of
synch.  This is most likely due to lost clock interrupts when doing the
heavy graphics work.

This particular machine is not a time server, so no harm is done.
