Answer the following questions in about 30 words.

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?

This is due to the adoption of IST or Indian Standard Time. According to the government, the time across the country would not be measured by the local longitude; instead it would be governed by the time shown at 82°30’, which is the meridian passing through the centre of the country. Hence, despite the early rising sun in the eastern end of the country, the time shown by the watches in Kohima and Delhi is the same.
