Running on my Windows PC (ntpd 4.2.7p241) I get:

C:\>ntpdc -c kerninfo pixie
pll offset:           0.001216 s
pll frequency:        27.793 ppm
maximum error:        0.005504 s
estimated error:      2e-006 s

pps frequency:        27.793 ppm
pps stability:        0.010 ppm
pps jitter:           0.002575 s

Whereas logged into the FreeBSD 8.0 system (ntpd 4.2.4p5) I see:

pixie-ii# ntpdc -c kerninfo

Not only do the numbers look different, but the 2107 status isn't decoded. 
Your thoughts?

Thanks,
