A more accurate statement is that a real time event can be labeled with measured time, M, by local device that keeps the TAI(h) time scale, and the TAI(h) time scale can be steered to UTC(k), GPS, or another broadcast time scale. The letter "k" designates a recognized time laboratory while "h" represents some hacker of unknown competence. Subsequently, when the IERS publishes the appropriate bulletin, a refined measured time, M', can be derived which removes the error in UTC(k), GPS, etc., but not the error in steering to that standard, nor any other
measurement errors made by the local device.

Indications have been that BIPM will disagree violently with that
statement.
And what's wrong with simply ignoring them after telling them to STFU?
