Dave,
>>In the famous equation you cite, add one second on the path from t1 to
>>t2 and a corresponding second on the path from t3 to t4. The additional
>>second cancels out. offset = {[(t2 + D) - t1] + [t3 - (t4 + D)]} / 2
That does not compute.
In your equation, D delays the receive timestamps (T2 and T4)
In the example, D delays Sue's timestamps (T1 and T4)
I fear the question stack has pushed too deep to ever pop out to the original goal.
(IE. Understanding why CP1 and CP2 are (or are not) a necessary part of the spec.)
73's,
Stuart
