How do you differentiate time zones?
A simple calculation is required to get the number of degrees in each zone. 360 degrees can be divided by 24 hours in a day to arrive at the answer of 15. In other words, each time zone is comprised of 15 degrees of longitude and differs from each other by an hour.
What is the formula for time zones?
To find the time zone in hours of a particular location, you can take the longitude -- in degrees -- and divide it by 15. So, for example, 75° E would be 75/15 which equals 5. That translates to the time zone being 5 hours ahead of UTC or GMT time, which can also be labeled as UTC+5. Let's do another one.
What causes difference of time between two places?
It is either due to a relative velocity between them (special relativistic "kinetic" time dilation) or to a difference in gravitational potential between their locations (general relativistic gravitational time dilation).
