International Meridian Conference
On 11 October 1883, a convention of railroad executives met in Chicago and agreed to the implementation of five time zones in North America, using as a basis Greenwich Mean Time. Before the invitations to the Washington conference were sent out on December 1, the joint efforts of Abbe, Fleming and William Frederick Allen, Secretary of the US railways' "General Time Convention" and Managing Editor of the "Travellers' Official Guide to the Railways", had brought the US railway companies to an agreement which led to standard railway time being introduced at noon on 18 November 1883 across the nation. Although this was not legally established until 1918, there was thus a strong sense of "fait accompli" that preceded the Washington conference, although setting local times was not part of the remit of the conference.
Time in Australia
The colonies enacted time zone legislation, which took effect in February 1895. The clocks were set ahead of GMT by 8 hours in Western Australia; by 9 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 "Western Standard Time", "Central Standard Time", and "Eastern 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.
