Question

If every state follow its local time then what problems would rise?

Answer 1

The local times of places which lie on different meridians are bound to differ. The sun rises 2 hours earlier in Arunachal Pradesh as compared to Gujarat in the west. This causes a time loss of 2 hours from Gujarat to Arunachal Pradesh. To avoid confusion due to time differences and to have a standard time for reference, the time along the meridian 82°30'E passing through Mirzapur in U.P. has been taken as standard time for whole country.
PROBLEMS ARISE:
During travelling from one state to other.
