Guys,
May I suggest you review the definitions of system offset (THETA), root
distance (LAMBDA) and system jitter (PSI) in Section 11.2 of rfc5905.

The "offset" may be better, but offset is not the offset from true
time, it is the offset from the sum of the upstream server time and
the measurement errors for the last poll. There should be no way of
measuring the error from UTC. The fact that you can do so, to some
extent, is due to the NTP algorithms being less than ideal.
