The delegates accepted the recommendation of the 1884 International Meridian Conference to adopt Greenwich Mean Time (GMT) as the basis for standard time . </P> <P> The colonies enacted time zone legislation, which took effect in February 1895 . The clocks were set ahead of GMT by eight hours in Western Australia; by nine hours in South Australia (and the Northern Territory, which it governed); and by 10 hours in Queensland, New South Wales, Victoria, and Tasmania . The three time zones became known as Eastern Standard Time, Central Standard Time, and Western Standard Time . Broken Hill in the far west of New South Wales also adopted Central Standard Time due to it being connected by rail to Adelaide but not Sydney at the time . </P> <P> In May 1899, South Australia advanced Central Standard Time by thirty minutes (see above), disregarding the common international practice of setting one - hour intervals between adjacent time zones . In doing so, South Australia also adopted a time meridian located outside its boundaries--another departure from international convention . Attempts to correct these oddities in 1986 and 1994 were rejected . </P>
