ATSC and DVB-T (DVB in general) are devoid of a 64 bit (or 80 bit) clock 
packet (based on NTP and 'Unix Time').

For people to be forced to rely upon GNSS (Glonass, GPS, Galileo) for a time 
signal is rather immoral when TV transmitters (and radio too, remember RDS) 
pump out many megawatts of signal each day (globally).
