Our planet is divided in 360 meridians (those vertical lines on a globe) by which we measure longitude. There is a 0 (zero) meridian and it passes through Greenwich, England (near London). It's from there that time zone counting starts.
Since there are 360 degrees of longitude and 24 hours in a day, each time zone is 15 degrees (360/24) wide. Yet, the first time zone doesn't start at 0 meridian, but it streches from 7,5 degrees west to 7,5 degrees east of Greenwich (so that England can be in one zone). From 7,5 degrees west or east longitude, you have another time zone beginning after each 15 degrees, both east or west.
And that's it. There are some modifications in some places in the world, but this is the general rule. :)

You can go online and download a worldtime clock but if you actually want to know how it works in terms of where you are in the world you can check by looking at a picture of the world in an atlas.
I dont know all the actual names etc it was my sister-in-law that showed me!
If you look at the map you will see a series of lines going across it, these lines represent different areas & time zones. At the top of these lines it will tell you a time difference, ie. 1 hour, 2 hour etc and therefore you can tell the difference between other places!
I've explained this pretty terribly!
Soz!

pick a ball and lighten it with a lamp by one side. You'll see that one part is lightened, the other one is a shade. So people who live in the lightened side of the earth say "it's noon!", while people behind say "it's midnight!". Then, people in between say "for us it's twilight 'cause we see the sun close to the horizon".
Nations agreed to divide the world in time zones so that everyone can relate their time to the position of the sun as they see it from their own zone every moment.

Well, there are 24. You're in one. Half way around the world its the same time only 12 hours different(midnite, noon). If you know how far away another location is, or if you have a globe, you could figure out what time it is anywhere.
