What you are referring to as the "freeware ntpd" is actually The NTP
Reference Implementation from The NTP Project at the University of
Delaware. This is the original, and definitive, implementation of NTP.

The "xntpd" in Solaris 8 is based on NTP 3.x from The NTP Project and
uses NTP Protocol version 3. This version of NTP is no longer maintained by
The  NTP Project.

The current releases of The NTP Reference Implementation utilize NTP
Protocol version 4 and include many refinements, enhancements, and bug
fixes not present in earlier releases. The current releases are:

	* Stable: ntp-4.2.4p7 2009/05/18
	* Development: ntp-dev-4.2.5p195 2009/07/27
