for a full-time in the internet host, I get very close
synchronization:
[herrold@swampfox herrold]$ ntpq -p -n
remote refid st t when poll reach delay offset jitter

The rightmost three columns are in mSec. This is done with
this file:
[herrold@swampfox herrold]$ grep -v ^# /etc/ntp.conf | grep -v ^$
restrict 127.0.0.1

[herrold@swampfox herrold]$
This is a dual homed host, and does not offer timeservices to
others (the first three lines are interfaces on the host; the
10.0.0.0 carrying the mask lists the IP range of other units
permitted to query it -- as none from 10.0.0.0 can reach this
unit, it functionally does not offer queriable ntp services)
