> Australia has decided to redefine its legal time scale.

The bill was introduced today.
Details of Bill 11 are found here.

The text of the bill is here$FILE/b04-133-16-p01.pdf

It defines UTC as being determined by the BIPM.
Nowhere is the ITU-R mentioned.

The BIPM says UTC is based on TAI, which is acknowledged to be their
own responsibiliy, and leaps as determined by the IERS.

So it remains unclear who ultimately controls the fate of civil time
in New South Wales. But the explicit mention of the CGPM endorsement
from 1975 could be interpreted to mean that NSW expects that UTC
should conform to mean solar time, and thus it should have leaps.
