TIME - Imaginary time - Time Machine & Etc

Stehen Hawking's exosition on TIME -travel through Quantun Universe ( TV Channel ) was very Interesting . On this issue, I venture here aan analogical Indian Mythological story comparing Cosmic-Time (Maha-KaaL ) with Solar or Earthly time (all Planetary times has different & varable scale or 24x7).
The Story :
Once Vishnu the creator of the unverse summonned NARADA ( vishnu's Ambassador for our World ) and asked him to go to the world and get some water from certain River (must be the Ganges) and gave him only half an hour Time. Narada obeyed the command but while returning fell in love of a villege girl; married her ,had cildren and was living very happily with a few grand children, perhas . He was now a senior Citizen and enjoying Pension (maybe). It was more than 50 years (IST) on the Earth.
Suddenly the Lord Vishnu called him up from Brahmalok (Sura Cosmos -Area), scolded Narada thus: 'Narada I sent you for some water from the world and gave you half an hour time and that half an hour is almost running out !. come on hurry up .'
Narada got a hurricane whirl in his head thinking my lord! I have lived almost 60 yrs. onn earth, a full life and it is still half an hour on Brahmalok ! ....and he hurried back to his time-travel-machine.
[[I know even EINSTEIN would have loved this report and Hawkings must be re-calculating his 'Imaginary -time '.{ Narada Bhakti Sutra (maybe ) ; told as I remember ]
