Hi, anyone else is having problems with ntp servers based on gps receivers? Both ours are drifting away since yesterday, and are now reporting some stardate around 2021 :-( One is a TrueTime NTS-90-GPS and the other is a similar model from the same brand.

We have a TrueTime NTS-100, and I've just checked - it's reporting the correct time.

Yes, I exchanged e-mail with an operator in Auckland about it yesterday when I noticed some of the NTP clocks stopped chiming. Only TrueTime brand clocks seem to be affected, but there doesn't seem to be a clear answer what version or type of firmware has the problem. Some clocks jump forward 1024 weeks, even though they report the same software version as clocks which don't jump. It took me a while to figure out what was happening because Solaris 8 has a kernel tick adjustment bug causing the clock to run out of control on certain models, so NTP was going crazy trying to discipline the runaway clock.

Dave Mills wrote a brief essay on NTP, the role of proper configuration and the 20-year time warps last night. If you don't read USENET anymore, you can get a copy via google. http://groups.google.com/groups?hl=en&selm=3C32924F.994E1D01%40udel.edu

It seems it's about... time I learn more about ntp. In the meantime I've modified my net to use the national atomic clock. Hopefully that will not drift.
