Is there a way to force vdr to first update system time to transponder time as design and after look if something is really scheduled ?
You could use a tool like dvbdate to update the clock before starting VDR.
If you have a permanent Internet connection, or at least some local LAN server with a better clock, you can use NTP to synchronize the clock.
Another idea is to use some tool to correct constant clock drift. This should get your clock quite well, if the clock drift is constant, like 5 minutes per day. (The ntpd time server has a built-in drift correction, but of course requires another exact time source)
