Answer 2

Answer:

IST stands for Indian Standard Time. India is a vast country and there is a time difference of 2 hours between the easternmost point and westernmost point, from Arunachal Pradesh to Gujarat respectively. To pick an average time which is very close to the time at all regions in the country, our country has chosen the 82° 30' E meridian as our standard time meridian. For international and national uses, the time at this meridian passing through Mirzapur in Uttar Pradesh is used.
