We need a standard meridian for India because there is a time lag of about 2 hours between Gujarat and Arunachal Pradesh. To avoid confusion of time in different states , India adopted a standard meridian which is 82 degrees 30 E and it passes through Mirzapur in Uttar Pradesh.
The local time of places differs from one place to another. In India, we find a difference of about 1 hour and 45 minutes in the local times of Dwarka in Gujarat and Dibrugarh in Assam. Hence, it is necessary to adopt the local time of some central meridian of a country as the standard time for the country. The longitude of 82½° E (82° 30’E) is considered as the standard meridian.
