About these time zones
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).
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.
