I constantly struggle when I must calculate the difference between two times. Such as:

6:30PM - 4:52AM = ?

And then of course it gets extremely frustrating with timezones. Such as:

6:30PM EST - 4:52AM CST = ?

And then of course of course, we also have dates. Such as:

March 12 6:30PM EST - March 10 4:52AM CST = ?

I would expect the answers to be in years, months, days, minutes, seconds format. Such as:

1 day, 3 hours, 52 minutes

If this is too big of a bite to take. I would appreciate whatever level you can and are willing to tackle now. Thank you for considering!

(Just look how many "duration between two times" google searches and tools there are. I think this is a medium-sized unsolved problem you could win.)
