Which is the Standard Meridian of India?

The meridian or longitude used to define a country's time is called the "standard meridian." All over the nation, the standard meridian is fixed. In accordance with the various methods of measuring longitude, the standard meridian varies for every nation. Mirzapur, Uttar Pradesh, is the point where the Indian meridian runs. 

The nation as a whole recognizes it as the standard time. As of 82°30'E, the longitude begins. All of the clocks in India are synced with the meridian that serves as its standard. We all keep the same time by using the Indian meridian as a reference. Each nation observes a unique time zone and uses a separate standard meridian, like India. Different locations have different local times. The local times of Dibrugarh in Assam and Dwarka in Gujarat differ by around 1 hour and 45 minutes in India. As a result, the local time of a country's central meridian must be adopted as the nation's standard time. As the standard meridian, 82° 30'E longitude is used. The local time indicated or mentioned at this meridian is regarded as the national standard time. This is called the Indian Standard Time.

For example,

There would be some discrepancy in the time zone of the other adjacent nations if it is morning in India and some of its neighbors and it is 5 AM in India. This occurs as a result of the different standard meridians.
