My ntp.conf file is much simpler than than. It just has a "driftfile"
line and a few servers are defined. There are no "restrict" lines.

I was looking at their web site yesterday. They look good, and CDMA
would be the way to go for us. But, I think I would have problems
getting my boss to pay $2500 for what amounts to a fancy clock. I will
try, though. A cheaper version would be preferable if available.
