Just variation of Earth’s rotational speed over time, AFAIK. -- TAI is SI second ticks, UTC is
corrected to rotation by leap seconds.  Currently they are 37 seconds apart.

Ah, leap seconds.  I work for an observatory.  Some things are in TAI and
some are in UTC.  At least now I know what to look for when something is 37
seconds off.

Isn't about that the transit of the Moon or something?
