The Importance of World clocks
By Charles Wilkinson

A world clock is defined as a device to measure and display time from different areas of the world. A typical world clock determines time from a specific place by dividing the areas into zones. Each of these zones corresponds to a group of states or countries, which share the same time.

With today's busy and hectic world, the importance of world clocks has increased dramatically. For businesses that cater to global clients, it is important that you consider their time zones, wherever part of the world they reside. This way, your company could set a meeting by checking a world clock and ensure that you will be able to contact your clients at a time they are comfortable.

A world clock can also be used for personal reasons. If, for instance, you have family members living a continent away from you and you want to contact them, you can use a world clock to determine if they're in the office, having dinner or sleeping.

World clocks are available as digital clocks displaying numeric data or analog clocks with the traditional moving hands. Regardless of design, world clocks are labeled with a time zone or the name of a city in the world. Some world clocks are designed with a map of the world and a light projector, which represents daytime.

Today, world clock software has been developed for computer use. This is particularly important for business, freelancers working for companies overseas and families who contact their friends and family members using the Internet.

Understanding World Clocks and Time Zones

When using world clocks as a time-keeping device, it is important that you understand that there are twenty-four, different time zones in the world since the Earth rotates in a 24-hour period. For this reason, the sun can be rising in your area, while it is setting in another area.

In 1840s, Great Britain set a standard time for the whole region known as “Greenwich Mean Time (GMT). Being the first country to have its own time zone, Great Britain made the 0-degree Royal Greenwich Observatory the center of its time zone.

When global clocks became accurate and communication went global, the idea of time zones was introduced and used the Royal Greenwich Observatory as the starting point for determining all the 23 other time zones.

Today, these 24 time zones make it possible for world clocks to work as accurate as they can, providing users with exact the exact day, hour, minutes and seconds of any place around the world.
