Greenwich Mean Time was the same as Universal Time (UT), a standard astronomical concept used in many technical fields, until the introduction of UTC in 1972.
Current time in the United Kingdom: UK time now

Eastern Time
Eastern Time (ET) is a general term used to describe the areas that observe either the Eastern Standard Time (EST) or Eastern Daylight Time (EDT) in the United States and Canada. ET is not static but switches between EDT and EST.
ET is also used somewhat as a de facto official time for all of the United States because it encompasses 17 U.S. states in the eastern part of the contiguous United States including the capital city Washington D.C., the most populous city New York and half of the country’s population.
In the United States nationally televised programs, evening newscasts, talent and awards shows, and any other nationally televised event that airs live on American television during prime time and on the weekends are broadcast live in the Eastern Time Zone. Major professional sports leagues MLB, NBA, NFL and NHL also provide their game times in Eastern Time, even if teams are from outside of Eastern Time.
Countries using this time zone: Bahamas, Canada, Cayman Islands, Haiti, Jamaica, Mexico, Panama, Turks and Caicos Islands, United States
Principal Cities: The largest city in the ET time zone is New York City in the United States, with about 8.804 million people. Other major cities in this time zone include Toronto, Montréal, Philadelphia, Port-au-Prince.
French: HNE - Heure Normale de l'Est
Spanish: ET - Tiempo del Este, ET - Zona Sureste
