Time in The United States - National de Facto Official Time

National de Facto Official Time

The Eastern Time Zone is commonly used by the national media and other organizations as somewhat of a de facto official time for all of the United States. National media organizations will often report when news events happened or are scheduled to happen in Eastern Time, even if they occurred in another time zone. TV schedules, especially those that list events that are broadcast live across the country, are also almost always posted in Eastern Time. The major professional sports leagues also post all game times in Eastern time; thus, for example, the start time of a Los Angeles Dodgers–San Francisco Giants game usually is still posted by Major League Baseball and the national sports media in Eastern Time, even though the game location is covered by the Pacific Time Zone.

However, the United States currently does not use any sort of national railway time like the railways in Russia; airports, railway stations and other modes of transportation follow the local time.
