find anything other than that systems with high load my loose time.  One of
my oldest machines has had this problem for a long time it works good for
about a week with a new cmos battery and then starts loosing 2 - 5 seconds
per hour.  If it wasn't time sensative it would be ok, but some of it's work
is time sensative so I sync the time 4 times per day.
