500PPM is the limit to the rate at which the clock can be slewed in most operating systems. Recompiling will not help. Modifying the O/S kernel and rebuilding the kernel MIGHT help. (I've never heard of anyone having done this.) If the system is that badly broken it's probably easier to have the hardware repaired. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
