That assumes that UTC can be represented as a real number with the
standard topology, which doesn't seem to be what TF.460 says. It
describes each second as labelled, which means that you have to
stitch together all possible unit intervals for each second with
some topology, and then you can ask if the path taken by UTC through
this space is continuous.
