Each longitude is equal to 4 minutes. This can be calculated from:
There are 360 longitudes. And the earth takes 24 hours (=1440 minutes) to complete one rotation; i.e. 24 hours are equally divided in these 360 longitudes.
So, dividing 1440 by 360, gives us 4 minutes.
Thus, with each longitude we move by 4 minutes.

The earth has 24 time zones with each one being 360/24 or 15 degrees between each longitude line.

The sun or the earth movement around the sun. The sun rises on the east... accordingly in a eastern longitude it is earlier wghen compared to a western one. The world is divided in a time convention called time zones. The base is the time of the Greewhich observatory in the UK (GMT) and then it goes with minus to the east and with more to the west (minus or more hours when compared to the base)
