Hi David, I am wondering is there any other means to profile NTP

of two machine?

Thanks, but I mean something which do not rely on the output of

My NTP Monitor uses NTP network calls to determine the offset of the PCs -
it doesn't use ntpq. However, in that sense, it does rely on the output
from NTP.
What problem are you trying to solve, and how

You need access to the source code of the clock interrupt service
routine and the ability to directly right to something like a

The NTP problem, is because my ISP (Demon) has been bought out by CW,

It looks bad. Normally you would expect it to be taking its time from
