I also don't get why ntp isn't barfing out like it normally does after it goes out more than 1000s.
The ntp daemon will create itfor you once it's computed a good frequency estimate. up vote 11 down vote favorite 3 When the ntpd daemon is running, the file: /var/lib/ntp/ntp.drift gets updated periodically. One other thing: if you execute ntpdate when the NTP daemon is running, you get Code: ntpdate 30 Apr 10:29:54 ntpdate: no servers can be used, exiting Look familiar? You MUST have at least 3, better 5.

So, it seems you either need to maintain an alternative config file without either of those options enabled specifically for use with something like ntpd -q -g -c /etc/ntp-quit.conf, or stick Sticking with openntp.END EDITI searched the forums and followed directions on both the forums and the wiki.
How? This is a fake driver intended for backup\# and when no outside source of synchronized time is available. I'd recommend running your hardware clock on UTC if you're planning on using ntp. What units is the drift expressed in?
If however, you want to go for a smooth correction, you can write a script that ntp has to pass through before setting the system time.

Get your system clock (the software clock) close to the "real" time.

I can't remember if it was for security reasons or otherwise though.
