[ntpwg] Updated NTPv4 Protocol Specification

[rich.osman at nsn.com]

Brian,

Actually, I believe there was rough consensus around the use of the
first bit of the start of frame regardless of protocol. I certainly
agree this is the best point and only offered the option I did because
of my perception of it's probability of achieving consensus.

What I'm not sure of is whether there is consensus around including text
at the end of section 4 "Definitions."  I'd offer: "The timestamp
reference point is the leading edge of the first bit of the start of the
IP frame." as the text to include at that point. 

I don't know if it's too late or sufficiently critical to decide at this
late date.  I was primarily responding to a comment by Stewart (or was
it Yakov) in Chicago, though there is value in this issue for a number
of applications that interest me.  

While I'd like to see this resolved, I don't see earth shattering
consequences if it's not.
