By the nature of its charter the ITU-R is incapable of serving

In this case guidance, and time for engineers and systems to adapt

Is the DUT1 broadcast a vestige of the past, or is it actively used?
I belive that the British 60kHz Rugby transmitter regularly have
been transmitting out-of-date DUT1 values due to sloppy procedures.
That would indicate that it is
