Using the "ntpq -p" command (of which I was previous unfamiliar) I was
able to convince myself that my xntpd was, in fact, doing its job. It
appears that my system is about 20 milliseconds off from its peers (more
or less) and that sounds about right to me. Given this information, I'm
not inclined to worry much about what is or is not in the log file!

This is a great list.
