Question

what is local time of Mumbai 73degress E
when greenwhich 0 degrees​

Answer 1

The longitude is almost irrelevant. The time at Mumbai, 72°49′ E, is the same as the time at Kolkata at 88°22′E. And the time at Greenwich, a suburb of London, varies during the course of a year, while the longitude doesn’t.

The whole world is covered by time zones, so you need to find a time zone corresponding to your places. For Mumbai and Kolkata that’s clear: it’s IST, with an offset of 5 hours, 30 minutes from Coordinated Universal Time - Wikipedia, the basis of time zones. Greenwich, a suburb of London, is in the United Kingdom, where the time zone in the winter is Greenwich Mean Time - Wikipedia, and in the summer it’s British Standard Time. The UK is the only country in the world to use GMT, which is almost the same as UTC. BST is one hour ahead (GMT+1:00).

So when it’s 12:00 in Greenwich, the UTC time can be 11:00 or 12:00. The corresponding time in any part of India is 16:30 or 17:30. One time that it most certainly will not be is 16:48, the time you would get by assuming
