Question

While the sun rises earlier in the east, say Nagaland, and also sets earlier, how do the watches at Kohima and New Delhi show the same time?

Answer 1

While the sun rises earlier in the east, say Nagaland, and also sets earlier but the watches at Kohima and New Delhi show the same time because India follows one standard time all over its land. It is the time shown at the standard meridian of India. There is a general understanding among the countries of the world to select the Standard Meridian in multiples of 7° 30′ of longitude. Hence, 82°30′ E is chosen as the Standard Meridian of India, and the time along the Standard Meridian of India passing through Mirzapur is taken as the Standard Time for the whole country.
