Abstract:

We can now talk to anyone, anywhere at any time of day. Because of this we are generally aware that the time in England is different from the time in Canada or Australia. The planet has been divided into a system of imaginary lines. The vertical is called longitude, and the horizontal is called latitude. And it's longitude that is the foundation for world time zones.
