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.
