So +/- 0.05 sec (50ms) is OK? ntpd should have no problem with that. > All servers will be running RH 5.5.

Not even when "synced" to the Undisciplined Local Clock (127.127.1.x) aka "LOCAL". When ntpd is "synced" to "LOCAL" it just accepts the kernel's notion of the correct time. So when the kernel clock drifts ntpd will follow. -- Steve Kostecke <[email protected]> NTP Public Services Project - http://support.ntp.org/ _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
