[Tfug] ntpd problems - server losing an hour or more each day

[Bowie J. Poag]

Wow. That clock is way off..

The only thing I can suggest is make sure that you make sure your drift 
file in your ntpd.conf is working, and make sure you run it more frequently.
The drift will will only be useful if your system goes deaf to the 
outside world, but, at least you'll know how bad off your clock is.

Cheers,
Bowie
