I've just been playing back a recording from an hour ago and was surprised to find the first few minutes were missing.
I eventually noticed that the time on the box was 9 minutes slow (so the recording had started 9 minutes late).
I have the box configured to get the time form the transponder, but it turns out that at boot time (according to /var/log/messages) it runs ntpdate to set the time via NTP:
May 15 18:06:38 mbtwin daemon.notice ntpdate[402]: step time server 78.109.188.115 offset 1431709536.911342 sec
The unfortunate thing about that is that currently that time server is running 9 minutes slow!
root@mbtwin:/var/volatile/log# ntpdate -q 78.109.188.115
server 78.109.188.115, stratum 2, offset -542.344368, delay 0.05296
15 May 20:14:36 ntpdate[7487]: step time server 78.109.188.115 offset -542.344368 sec
So,
where is this server setting configured - it would make more(?) sense to query multiple servers (such as using pool.ntp.org instead)
why did the "from Transponder" setting have no effect once the system was running? It had been up for nearly 2 hours and was still 9 minutes slow until I fixed it by hand just now (which I had to do from the command line as the Enigmna2 GUI doesn't give you any option to set the time "now").
