But how could he get a 16 second offset, after starting out with a .1 s and 1 s offset. At 500PPM, 16 sec takes 32000 sec (10 hr) to accumulate which is poll interval 15. Ie, I cannot see how ntpd could have allowed that huge an offset to occur. In the posts I saw that all of the sources were off by 16 sec, not just the Oncore. > > Would be interesting to know if this happens on every ntpd restart or > only shortly after the GPS unit was powered up.
