I must say (as an NTP user) that I don't understand: why don't you just allow xntpd to use the RTC as a local clock and let xntpd slave ths system clock with it ?

I seem to remember messages on this list a few weeks back stating fairly clearly that several parts of Linux already rely critically on all TSC being synchonized (and thus Linux ensuring that it is the case).
