Thanks, Dave.
I see that reference 25 points to:
Abstract:
http://www.eecis.udel.edu/~mills/database/rfc/rfc1305/rfc1305a.pdf
Body: http://www.eecis.udel.edu/~mills/database/rfc/rfc1305/rfc1305b.pdf
Appendices:
http://www.eecis.udel.edu/~mills/database/rfc/rfc1305/rfc1305c.pdf
On page 11 of the body, the word "precision" is used in the context where
I would use "resolution". It isn't used in the sense of "how close to the
correct time is this clock", which I might call accuracy. Perhaps it
would be helpful to have these terms defined somewhere? Perhaps the terms
are used differently by different cultures, even!
Cheers,
David
