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.
East Coast bias
The North American continent is divided into seven time zones, spanning 6½ hours from Alaska to Newfoundland. Most of the continent's population (including all of the major professional sports teams) is concentrated in the four time zones of the contiguous United States and Canada west of the Maritimes; this, however, still poses a significant obstacle in that the easternmost sports teams are a full three hours ahead of their western counterparts. For sports that play in prime time according to local time zones (as is the case with ice hockey, baseball, and basketball), this can result in games played on the West Coast starting after 10 p.m. Eastern time (and not ending until around or after 1 a.m.), while the East is sleeping and after printing deadlines for the next day's newspapers have passed. Gennaro Filice of SI.com wrote that Major League Baseball's West Coast night games are ending as "the country's most influential scribes are catching Z after Z." John Buccigross of ESPN notes that a lot of people in the East are asleep when National Hockey League's West night games are going on, resulting in lower television ratings for those West Coast games, which in turn contributes to the lack of national broadcasts of West games.
