These were all recently installed, and talk to a Stratum 2 server.
It is a P133: (1.1 release)
offset:               -0.000899 s
frequency:            -6.014 ppm

The Sparcs have only had xntpd running for 3 days or so. (obviously from
about July 28 on the SS10)  I'm not sure how that affects accuracy.
Also, I plan to update the LX to -current ASAP, so I'll report if that 
causes a significant change in ppm.

Are you building your kernel with just the sun4c or sun4m code?
