It's a problem with POSIX, not UTC.

UTC is monotonic.

The problems are that UTC is unpredictable, and it breaks the standard
labelling of points in time that was used for hundreds (arguably
thousands) of years before 1972.

You mean back when seconds were rubbery, and before the earth's
rotational speed could be easily and accurately measured, or at least
when the wobbles at that level of accuracy became so noticeable that
they could no longer be ignored?
