[ntp:questions] Re: HowTo calibrate system clock frequency using NTP

Hello Professor Mills,

I have a lot of respect for the delicate and sophisticated NTP 
internals. Actually too much respect to get in touch with them.

Rather I'm using NTP as a tool. A tool that measures (or helps me to 
measure) the system clock's frequency error.
