Why is that?
If the SI second were properly tuned to the mean solar day, and the
secular slowing were eliminated, there would be no need to mess about with
the civil time scale, because the random accelerations and decelerations
would cancel out in the long run. Of course, we'd have to tolerate larger
differences between clock time and terrestrial time, but we'd expect that.
