ATSC time is always late ?
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).
Immoral? That's a bit strong, innit? You don't NEED to rely on
satellites for time signals. There are many LF radio time signals, such
as WWV, WWVB, WWVH, CHU, MSF, DCF77, and others. CDMA cell phone towers
broadcast a time signal.
Immoral sounds good to me. If you can point me in the direction of an LF
receiver that works in Australia I might reconsider.
Or a CDMA receiver at a price similar to one of those LF receivers that
everyone raves about.
And where did the Lord assign anyone the duty to provide you with a time
signal? The United States Government built, launched, and maintains a
network of twenty-seven GPS satellites at no cost to the Australian
citizen. A Garmin GPS18-LVC timing receiver will cost you less than
$100 US.
The only "morality" involved is the questionable "morality" of believing
that the world owes you a time signal at no cost to you.
Perhaps the Japanese can help you out. I seem to recall that JJY
broadcasts a time signal; ISTR I heard it on 5MHz when I was stationed
in Japan.
