A one second slip I could understand-- eg Gamin 18x reporting over 1 second after the associated second would lead to that. But a computer advancing at an hour per tick is way beyond that. Perhaps the 1 second slip tickled a bug in ntp with the LOCL clock-- where the system then saw the GPS as a false ticker, went to LOCAL with a bad rate, and compounded the rate error by some sort of runaway process. > > Cheers, > David > > _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
