Answer:
Explanation:
Indian Standard Time (IST) represents the time observed throughout India, with a time offset of UTC+5:30. India opted out of observing daylight saving time, (DST) or other seasonal adjustments, although briefly using DST during the Sino–Indian War of 1962 and the Indo–Pakistani Wars of 1965 and 1971. In military and aviation time, E* ("Echo-Star") designates IST.

Indian Standard Time calculates on the basis of 82.5° E longitude, just west of the town of Mirzapur, near Allahabad in the state of Uttar Pradesh. The longitude difference between Mirzapur and the United Kingdom's Royal Observatory at Greenwich translates to an exact time difference of 5 hours 30 minutes. A clock tower at the Allahabad Observatory (25.15° N 82.5° E) calculates local time, though the National Physical Laboratory, in New Delhi has been entrusted with the official time-keeping devices.
The longitudinal extent of India is from 68*EAST longitude and 97*EAST longitude.This amounts roughly to 30*. The 82½*EAST longitude is considered as the standard meridian of India.The local time along this longitude is generally considered as the common time of India.This is known as Indian Standard Time. Indian Standard Time is 5.5 hours (5 hours 30 minutes) ahead of Greenwich Mean Time(GMT+5.5).
