Well, TAI is produced by the BIPM, UTC - TAI is decided by the IERS,
and the 26th CGPM have approved a definition of UTC (which implicates
that it is the business of the BIPM to give the definition).
The ITU decide how UTC is used in their standards, and in particular,
how UTC is disseminated with radio signals; they do not (re)define UTC.
There is a Memorandum of Understanding between the BIPM and the ITU that
regulates all this (and promises cooperation) in legalese:
