World Time ZonesEach time zone is approximately 15º, and is separated by one hour from the next zone.
For political and commercial reasons, some regions are included in a neighboring zone.
To calculate time in the different zones,
find the number of zones that separate on region from the other.
Then calculate the difference. See Time and Date.com for more information.
