You are tracking the wrong problem. The problem is NOT ntpd. The problem is the time you are getting from gps/gpsd/shm. That is where you should be looking, not ntpd. ntd has been used for about 40 years now. It works. Similarly gpsd. Your boss is telling you to fix something that is not broken, wasting whatever salary they are paying you. Do they really have solittle for you to do that is useful? You have not told us what operating system you are using. Or anything about your systems, except some are old (3mo?, 3yr? 10 yr? 30 yr?) _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
