So, why not just adding a parser to linux-dvb driver which compares the time signal by the DVB transponder and the PTS/PCR/SCR/... and rewrites time stamping relative to 00:00:00 am UTC? That way an application could store/handle 24 hour chunks and just store the current date of that chunk in a table. Rene
