That describes the RTC, and may not even be valid for HPET systems. The clock that ntpd disciplines is not based on a 32kHz watch crystal, but on a much higher frequency crystal. Historically, the primary purpose of the latter crystal is to provide a logic clock for the processor and memory, not for time keeping. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
