It wasn't about an hour ago. At least not when you threw ntpdate at it:
thor:~$ ntpdate -q blackhole.arlott.org.uk
server 84.92.75.21, stratum 15, offset -210105193.104270, delay 0.18675
28 Aug 20:33:12 ntpdate[11281]: step time server 84.92.75.21 offset
-210105193.1
Doesn't exactly look good, does it?
At the moment it is a) again synced to its DCF clock (it was not at the
time of that ntpdate, although it *was* synced to one of the remote
servers):
thor:~$ ntpq -p blackhole.arlott.org.uk
remote refid st t when poll reach delay offset
jitter

and b) it does it again:
thor:~$ ntpdate -q blackhole.arlott.org.uk
server 84.92.75.21, stratum 15, offset -210111428.429590, delay 0.09758
28 Aug 22:17:10 ntpdate[11984]: step time server 84.92.75.21 offset
-210111428.429590 sec
And 'thor' is my own stratum 1 NTP server (Motorola Oncore M12).
The boz is *not* OK.

Marco.
