IST is a meridian of longitude. It is at a distance of from the Greenwich towards the EAST. It passes through ALLAHABAD which is the approximate centre of India.

This meridian of longitude (82.5°E) is 5 and a half hours ahead from the time at Greenwich. India has the IST as it's standard time because if it wouldn't have been there, the country would have difference of hours (as India is a large country and has a large East-west extent --- there's a difference of hours from Gujarat in the west to Assam in the east). Hence, IST is an important meridian of longitude.
