But doesn't the HAL clock also support _both_ a fixed/baseline clock
frequency adjustment, and a temporary adjustment to be applied over the
next N time slices/seconds?
I.e. pretty much exactly what NTPD would like, if only there was a
highres interpolated system clock as well?
PS. I might be misremembering, it might have been the NetWare 4 clock
which had those fixed/temporary adjustment levels...
