My "radio time code" system never fails: I have a shortwave

all my clocks and watches at the beep.

Works like a charm!

How do you know if there is a digital relay link somewhere in the
transmission train?
I used to rely on the teletext time that came with the VITS of analogue
TV, but all gone belly-up with digital MUX. In the UK we have the
ridiculous business of the genuine radio pips relayed onto the "radio"
sections of MUX TV, can be up to 10 seconds out via the codec delays.

If using a short wave receiver the signal is being picked up direct from a
station in the US. The only delay is the time it takes for the signal to
get to you by radio which is around the earth about 7 times in one second
and the delay of the sound from the speaker to you rear.
Both are much faster than you cn hit a button on the clock to set the time.
