Thanks, Dave.

I see that reference 25 points to:
  Body: http://www.eecis.udel.edu/~mills/database/rfc/rfc1305/rfc1305b.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!
