Indian Standard Time (IST) and Greenwich Mean Time (GMT) are two different time standards used in different parts of the world. IST is the time standard used in India, while GMT is the time standard used at the Prime Meridian, located in Greenwich, London.
Time Difference
The time difference between IST and GMT is determined by the geographical distance between India and London, and the rotation of the Earth. India is located to the east of the Prime Meridian, which means that as one moves from west to east, the time gets ahead.
