About these time zones
India Standard Time (IST)
India Standard Time (IST) is UTC+5:30 and is used across all of India as a single time zone. India does not observe daylight saving time, so IST never changes — but its difference from places that do (like US Eastern Time) changes twice a year.
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).
