It is possible that I am confused.
What ntpd gets from a clock source is a series of pairs asserting
"at system time X I believe it was UTC time Y".
Are you telling me there is no value in minimizing the time from X to when
the sample triggers a correction, and the variation in that time?
Basic servocontrol theory tells me that control lag is the enemy of
precision and tends to produce whiplash effects. Does that not apply here?
