Oh, I assumed that the timestamps on the telemetry where the timestamps
when the packet was actually transmitted by the satellite, not when it
was eventually decoded and uploaded.

Is there any way of knowing when the satellite transmitted the packet?
It seems that one could perhaps use the satellite uptime and number of
resets.

Then it seems that the last telemetry uploaded realtime was at Sun, 08
Nov 2015 23:30:36 UTC by VK5KJP (uptime=22007).

Your telemetry has uptime=22211, so it was transmitted by the satellite
some minutes later.

The passes
*Monday November 9, 00:05 through 00:25 UTC*
*Monday November 9, 01:45 through 02:10 UTC*
over NA were when presumably the IHU was to be turned on again, so I'm
not so sure what happened.
