What is described here is not what is conventionally called an island. An island is a system which does not and never has had a source of correct time. ntpd doesn't care about what the drift is in determining root distance. It simply takes the position that the actual local clock will be somewhere within +/- 15ppm of the value which would achieve perfect phase lock with true time. The assumed maximum reasonable error therefore grows at 15 microseconds per second. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
