The Digital Radio Mondiale standard for long/medium/short-wave digital audio
broadcasts (freely available for downloading as ETSI TS 101980) includes
time data, but like with RDS and DVB, the data format specification is not
really optimized towards high-precision clock synchronization and the DRM
COFDM demodulator needed is significantly more complex than the AM receivers
that decode the time signals listed above.
It is a shame that the NTP.org has not set up a working group to define
packet formats for RDS / DVB / DRM / AMSS.
