PPS (pulse per second) clock support in Solaris

I'm wondering if anyone here is using the PPS support in Solaris
to give accurate wall-clock timing from an external source, perhaps
to make a Stratum 0 NTP system or to keep several systems very
closely synchronised (better than NTP can)?
If so, how well does it work for you?

You should be asking this in comp.protocols.time.ntp

AIR the performance is hardware dependant.
PPS is part of NTP, so it improves the performance of NTP with a local
clock, such as a GPS receiver; it does not replace NTP.
What kind of accuracy are you looking to achive?
