It is a curious fact that UTC is specified by the ITU in recommendation TF.460 https://www.itu.int/rec/R-REC-TF.460-6-200202-I/en https://www.itu.int/rec/R-REC-TF.460-6-200202-I/en which also includes a specification for how radio time broadcasts should be formatted. I don’t know if any time signals actually use that format, tho.
That part of the ITU used to be CCIR, the international consultative committee for radio, which goes a little way to explaining it, but it is still strange that it isn’t the responsibility of the IAU, IERS, or SI.
