Explanation:
Greenwich mean time can be defined as the mean solar time at the greenwich meridian, adopted as the standard time in a zone that includes the british Isles. Indian standard time can be defined as the time observed throughout india and srilanka with a time offset of UTC+05:30.
Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London, reckoned from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon;as a consequence, it cannot be used to specify a precise time unless a context is given.
Indian standard time is the standard time of 82 and half degree east longitude passed through Allahabad. it is 5 and half hours ahead of GMT
