I have xntpd running on a number of different model Suns and IBM RTs and have noticed that the frequency drift is very different depending on which machine I look at. Here is what I have in /etc/ntp.drift on three of my systems: Sun 4/490 0.126807074 Sun 4/380 -0.043642800 IBM RT 6150 0.005678721 Here are a few questions I hope an NTP guru might be inclined to answer: 1) Are there any patches to SunOS 4.1.1 in the area of time keeping? I had heard that adjtime(2) was broken in some releases of SunOS but have not been able to confirm this. 2) Does the 4/380 really have a better clock that a 4/490? 3) What might explain the differences in the drifts between the Suns? 4) Does the IBM RT have a clock that is an order of magnitude better than a Sun? All of these systems have been running xntpd v1.3 for at least a week.
