The sun rise two houra earlier in arunachal pradesh as compared to gujarat because they are far distance from each other and the standerd unit of time for pass through mirzapur in uttarpradesh so the clock show same time

Answer 2

The Sun rises in the east. Time is ahead by 4 minutes every longitude while going towards east from the west. Jaisalmer is located at 68°7'E and the eastern most point of Arunachal Pradesh is at 97°25'E. The difference is of 2 hours (4×30°=120 minutes or 2 hours).
But the local time of 82°30'E is taken as standard time throughout the Country and all the watches in the Country run according to the time of 82°30'E.
