It isn't a question of absolute accuracy of the clocks, but of knowing
the time difference in two different places, which are in separate,
non-inertial frames. In practice, it is very difficult to keep two
clocks in absolute sync when they are located hundreds of miles apart on
the surface of the Earth. It is a complex problem in Relativity to back
out all the effects that introduce errors.
