A technical issue: broadcast time signals are phase-locked with the carrier, which is at some exact number of hertz. If the time pulses are every civil second, and that is now 1.000000015 s (as it was in 1961), it can't be synchronised with the (say) 60 kHz carrier that must still have exactly 60000 cycles per SI second.
The obvious solution is to transmit rubber time on a rubber frequency. -- Ashley Yakeley
