All,
What is the best offset that you have been able to attain with ntpd?
With a Garmin 18 LVC + LinuxPPS + Linux 2.6.17 + ntpd 4.20, the best I
can get is an offset of about 0.006 ms. This offset is never steady --
it drifts from positive to negative. Right *now*, for example, it is
-0.017 ms. I use this machine for real work and play (X, multimedia,
OpenOffice, etc.).
My delay is consistently 0.000 ms, and jitter is 0.001-0.002 ms, so
those are good. Is my offset good for a stratum-1 machine? Can
anything be done to minimize and stabilize the offset? Probably the key
factor is my activity on this machine, but is there anything else?

Here is what I get:
http://www.david-taylor.myby.co.uk/mrtg/pixie_ntp.html
This is with FreeBSD on a very old 133MHz Pentium 1, with 48MB memory,
dedicated just as a stratum 1 server. It's not /that/ good, I know, and
the GPS 18 LVC puck only has a view of half the sky (and less now the
leaves have grown on the trees).
Cheers,
David
