The time of a place depends on the longitude that passes through it. Therefore, the standard time for each country is usually taken as the time of the central meridian that passes through it. India has a vast longitudinal extent. Since many meridians pass through it, it is important to adopt the local time of one central meridian of a country as the standard time for the country. Thus, we need a standard meridian for the country. In India 82 ½ °E longitude determines the standard time. This is known as the Indian Standard Time. This longitude passes through Allahabad in Uttar Pradesh.
IST is the Indian Standard time
GMT is Greenwich Mean Time zone

Standard meridian time which is used in India is used to know the exact time among all the states
As different states have different times we need to select one particular time
So its IST (Indian Standard Time)
It is 5 1/2 hours ahead of GMT
GMT stand for Greenwich Mean Time
