I don't think he wants to do this.  He wants a time discipline system, 
that cannot be ntpd, that has a hard wired (pre-calculated) frequency 
correction that it never updates.  Most of the time only the frequency 
correction should be applied.  If the offset becomes too high, it should 
be rapidly cleared by something like the ntpd stepout mechanism, not the 
normal PLL.
