I can see a delay in the middle, but only a few minutes.  That could
well be normal processing times.

And something odd within my LAN; some 14 minutes going back and forth in
time.  All our PCs are NTP synchronised, and timezones are set right
(Adelaide, South Australia), so it's not a local clock issue.
