System Clock Sliding

One of my Linodes runs 184.108.40.206-linode22 and keeps perfect time without needing to run ntp.
File a ticket, too.
It's possible the host's ntpd is simply malfunctioning. Try an "ntpq -p $yourhost.linode.com". Some of them allow such queries; some do not.
If that were true, I wouldn't expect things to be corrected on a reboot, since it would still be getting the incorrect host clock. (Unless there's something in reboot processing that is doing a one-time sync like an ntpdate call from a network location).
Definitely sounds odd though, so once it gets resolved I'd be curious as to what it turns out to have been.
