Sorry to revive an old thread, but did anything ever come of this? The
project pages exist, but only minimally.

We propose the creation of an NTP project on OpenSolaris.ORG, affiliated
with the Nevada and Device Driver communities.
While historially SunOS 4 and Solaris have been platforms of choice for
NTP timekeeping and leading-edge development, Solaris has fallen behind
other platforms (notably FreeBSD) in recent years. This is due to a couple
of issues:
* The NTP daemon and utilities have seen much development in preparation
for the upcoming NTPv4 standard. Unfortunately, Solaris still ships the
ancient xntp (NTPv3) daemon.
* The NTP kernel support has evolved beyond the code currently in Solaris,
but those enhancements have not been picked up.
* There's a multi-vendor API for reference clocks that provide a
pulse-per-second signal (PPS API, RFC 2783). While Solaris has some
support for PPS devices, it failed to implement the PPS API
specification.
* Recent serial interface chips have seriously degraded NTP performance
due to extended on-chip buffering, so current systems have become
considerably worse for attaching serial reference clocks.
* The PPS serial support in the kernel is a private interface that was
not published in the DDI, so only onboard serial ports are supported.
* The TOD synchronizaton model is fundamentally broken in Solaris and
has resulted in unstable system clocks and wasted thousands of dollars
in support calls and needlessly replaced hardware.
* The adjtime system call slews the clock in a way that can disrupt NTP
time networks.
This project seems to remedy those problems and again turn Solaris into a
primary NTP deployment and development platform.
Project leaders will be Brian Utterback and myself.
