Correct, and that's why, in the very long term,
TAI is not suitable to civil time. And that's also
why UTC, whether implemented with leap
milliseconds, leap seconds, leap minutes,
or leap hours, is suitable to civil time. The key
thing about UTC is the C, the coordination
between atomic and astronomical time. The
UTC leap hour proposal honors that.
