What do EST and GMT represent?

New York to London time difference
When New York is on EST and London is on GMT, London is five hours ahead. A 9:00 AM start in New York is 2:00 PM in London in that standard-time pairing.
New York can show EDT and London can show BST during their daylight seasons. The United States and United Kingdom change clocks on different dates, so the gap can briefly be four hours around the transition weeks; use the selected date for accuracy.
