A basic question here is which timers are provided by the hardware, and 
if the timer the Linux kernel uses for timekeeping is properly supported 
by the Linux kernel, so that the undisciplined system time would 
increase at a constant rate.

If the undisciplined system time doesn't increase at a constant rate 
then ntpd will be unable to fix this anyway.
