One after the other:

thor:~$ ntptrace blackhole.arlott.org.uk
blackhole.arlott.org.uk: stratum 1, offset -0.000197, synch distance 
0.002905, refid 'DCFa'

That's OK.

thor:~$ ntpq -p blackhole.arlott.org.uk
      remote           refid      st t when poll reach   delay   offset 
  jitter

128.182

So is this.

thor:~$ ntpdate -q blackhole.arlott.org.uk
server 84.92.75.21, stratum 15, offset -210114885.349156, delay 0.10283
28 Aug 23:14:47 ntpdate[12137]: step time server 84.92.75.21 offset 
-210114885.349156 sec 


But this sure isn't!

And the three commands are executed in just about the same second...
