Thanks, Jerry.  My own accuracies on unloaded systems are similar:

  http://www.david-taylor.myby.co.uk/mrtg/daily_ntp.html

These systems are permanently logged in.

With your log-on & log-off, are there any scripts associated with the 
login process which might attempt to set the time - a NET TIME for 
example?  On other question - is there a difference in behaviour between a 
privileged user and normal user logging in and out?

Cheers,
