These are all Fedora machines which run ntpdate automatically as part of /etc/init.d/ntpd. The example above is from a machine behind the NAT which had been running for more than a week. The drift does not surprise me. In desperation, I have changed several of the machines behind the NAT to run ntpd -gq periodically, and stopped the ntpd daemon. Those machines are tracking the correct time fairly closely, within less than a second always. But I don't like this kludge and would love the find the right solution. -- Dave Close, Compata, Costa Mesa CA "There is no security on this earth.
