ntptrace.

/etc# ntptrace 
localhost: stratum 4, offset 0.000011, synch distance 0.18842
prometheus.cantech.net.au: stratum 3, offset 0.005146, synch distance 0.17824
poseidon.cantech.net.au: stratum 2, offset 0.006742, synch distance 0.16800
murgon.cs.mu.OZ.AU: stratum 1, offset -0.010337, synch distance 0.00111, refid 'GPS'

As you can see it's kinda like tracroute BUT for ntp.  It shows you each
serevr and the difference between your clock and theirs.

It will only work correctly after ntpd has been running for about 24 hours.

Yours Tony.
