The DVB broadcast TS includes a date & time signal. See: http://cvs.sourceforge.net/viewcvs.py/dvbtools/dvbdate/ From the readme... dvbdate is a simple program to set the system clock from the Time and Date Table packets in a DTT stream... 'dvbdate' just looks at the TDT information from the currently tuned multiplex and sets the clock to UTC. Jon
