The bill was introduced today. Details of Bill 11 are found here. http://www.parliament.nsw.gov.au/cgi-bin/isys/isyswebext.exe?op=get&uri=/isysquery/irl66ce/1/doc/#hit1 The text of the bill is here http://www.parliament.nsw.gov.au/prod/parlment/nswbills.nsf/0/de842061017f029eca256fb000169179/$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. -- Steve Allen UCO/Lick Observatory Santa Cruz, CA 95064 [EMAIL PROTECTED] Voice: +1 831 459 3046 http://www.ucolick.org/~sla PGP: 1024/E46978C5 F6 78 D1 10 62 94 8F 2E 49 89 0E FE 26 B4 14 93
