The last time I encountered it, it was an SNTP implementation, which means
it uses the over the wire formats, but doesn't implement all the 
algorithms.  One of the parts of the algorithm that many SNTP 
implementations don't implement is the the clock frequency correction
that was wanted here, although an SNTP could implement it and Open "ntpd"
might.

I would rather hope that someone from the open ntpd team does monitor this
newsgroup.  If they don't that would be another good reason to not use it.
(One can reasonably expect Microsoft's w32time team not to monitor here, or
to do so without responding, but I would hope that any open source implementor
would monitor and respond here.)

It's available pre-compiled for many platforms, including most Linux
distributions.

One of the reasons open ntpd was supposedly created is that the 
ntpd reference implementation licence doesn't fully meet the level
of free-ness required for Open BSD.  Although its fairly clear from
what Dave Mills has said that that is not the intention, he's not 
prepared to change it to clarify the point.
