No. The local clock simply trusts the time (Ie all offsets are defined to be zero) chrony takes the time as entered by hand by the operator and uses that to determine the offset. Of course that will not be terribly accurate ( a second is probably good), but if you are disconnected for a month, a second is probably pretty good accuracy. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
