Answer 5

It's daylight savings
JavaScript code by @Nikolay is one hour ahead
Java code by @Krishna shows UTC time
The answer changes depending on when you ask it
So is the final answer 22 or 23? 😕

Answer 6

Does it count the time when he travelled using the time machine?

Answer 7

I think the answer is 36 years, 10 months, 11 days and 6 hours...

Answer 8

@Nikolay
I also get 22 hours when I run your code. I don't understand what's going on, could it be due to different time zones or daylight saving?

Answer 9

well..., my JS says it's 22 hours.

[SOLVED thanks to Jafca] problem was one of the dates is within daylight saving 😃
