I am not sure about, how actually the time is set via VDR. Maybe Klaus can

AW: AW: [vdr] Problem with audio sync in playback - maybe caused by ntpd stepping local clock?

2006-10-20 Thread martin
Oh .. documentation by source :) *smile*

So, as far as i can read with my basic knowledge: if there is a difference
of more then 2 (don't know the unit, but I think it must be seconds), there
is a step in time. This can be sometimes not so nice, as it can give
consistency problems (e.g.: timestamps in syslog or file system)

So ntpdate would be the more advanced way, if you have a internet connection
available.

Regards,
Martin

If SAT time and internal clock differ by more than 2 seconds, and this 
time offset is reported twice in a row, the clock is set in one step.



This can be sometimes not so nice, as it can give
consistency problems (e.g.: timestamps in syslog or file system)


Even more severe. In case of very large time jumps, this can even lead 
to the famous video data stream broken and similar timeout issues.


Cheers,

Udo
