rom east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
The earth is divided into time zones by lines of longitude. There are a total of 24 time zones on Earth.
time zones are bordered by lines of longditude.

Meridian lines can be used to measure time zones. They split Earth into different time zones.
There are 39 time zones because of the sun and how the Earth lines up with it.

The earth is divided into 24 times zones. Divide 360 degrees by 24 and you will get the measure in degrees.
There are 24 time zones.

Earth is divided into 24 time zones. A time zone is a region with uniform standard time so areas near that location can keep the same time. Most time zones on land are offset by Coordinated Universal Time, or UTC, by a the whole hour (UTC-12 to UTC+14).
The earth is divided into 40 formal time zones, not 24 as might commonly be expected. See: http://en.wikipedia.org/wiki/List_of_time_zones for a complete list. Note that the number of time zones also varies with the season as some regions adopt daylight savings time (DST) while others (in the same time zone) choose not to use DST. This can lead to a seasonal increase or decrease in the total number of time zones. According to PHC there are 24 Major time zones

That is probably because we divide the day into 24 hours.
The earth is divided among 40 time zones (not 24) because before standard time started catching on in the late 1800s each of the thousands of cities kept its own time, and that started to get confusing as technology started making transportation and communication faster.
Because the Earth is tilted on its axis. Therefore, sunlight doesn't always hit in the same spot all the time, so time zones have to be out of proportion.
