The sun rises two hours earlier in Arunachal Pradesh as compared to Gujarat in the west
but the watches show the same time. How does this happen?
The longitudinal gap between Arunachal Pradesh and Gujarat is about 30°. Due to this, there is time lag of about two hours between these states. Since Arunachal Pradesh is in the east hence the sun rises earlier here compared to in Gujarat. The Indian Standard Time is taken from the time of Standard Meridian of India and hence, the watches show the same time in both the states.
