How to calculate the time difference between two cities
Ex.) When you move from Rome to New York:
[A] Rome time : +1 hour from GMT
[B] New York time : -5 hours from GMT
So the time difference between Rome and New York is:
[B] - [A] = (-5) - (+1) = -6 (hours)
You should move the hour hand back 6 hours.
