EST vs GMT
EST (Eastern Standard Time) runs at UTC−5 and GMT (Greenwich Mean Time) at UTC+0. GMT is normally 5 hours ahead of EST.
EST is the standard time (UTC−5); when daylight saving is in effect it becomes EDT (UTC−4). The live clock on this page always shows the current offset. GMT stays at UTC+0 all year round — it does not observe daylight saving time.
