About these time zones
Eastern Standard Time (EST)
Eastern Standard Time (EST) is UTC-5. Most places on Eastern Time use EST only in winter; from the second Sunday in March to the first Sunday in November they observe Eastern Daylight Time (EDT, UTC-4). People often write “EST” all year when they mean Eastern Time, so check which one is in effect.
Greenwich Mean Time (GMT)
Greenwich Mean Time (GMT) is the time at UTC+0. GMT and UTC show the same clock time; UTC is the scientific standard, while GMT is a time zone name. The United Kingdom and Ireland use GMT only in winter: in summer the UK switches to British Summer Time (BST, UTC+1) and Ireland to Irish Standard Time (IST, UTC+1).
