TIME TRAVEL IN INDIAN EPICS

Mahabharat: The earliest mention of time travel is found in the Hindu epic Mahabharat, when King Revaita travels to the heavens to ask Brahma's help in finding a suitable partner to his daughter. Revaita is shocked to find that while he was at heaven only for a few moments, eons have passed on Earth. King Revaita is effectively the first time traveller, and at the same time, testimony to Einstein's theory of relativity.

Apart from this there is also mention about time travel by Hanuman from Ramayana time to Mahabharata time where he confronts Bheem.
