The globe has 24 time zones. The earth rotates once every 24 hours. We set our clocks to the same time in each time zone. This allows for the sun to be overhead at noon.
You may have heard of Zulu time. It is also known as GMT or Greenwich Mean Time. When longitude and latitude came to be, GMT originated. Great Britain was the foremost maritime power. Greenwich Mean Time became the starting point for expressing longitude. Don’t forget about the international dateline. It is the point on the globe opposite the observatory. The prime meridian runs through southeast central London.
This point calculates time in all the other time zones. When it is noon at the Observatory, it is eight hours earlier in San Francisco.
Time zones are part of our daily life. We calculate time differences when we travel to other parts of the globe. Keeping track of time zones can be a challenge. We rely on charts to tell us New York and London are five hours apart.

The GMT watch saves the day for the international traveler. You know the time anywhere on the globe when you wear a GMT watch. It is an essential tool that keeps you on time and schedule.

Your GMT watch will tell you in an instant whether you will be waking up the house at 3:30 am before you place the call.
A GMT watch features a second hour hand. It rotates half as fast as the hour hand. This second hand rotates once every 24 hours. The hand that isn’t reading hours is also known as the GMT hand. It points to a time scale that reads to 24 instead of 12. In some instances, the GMT hours located on the bezel.
The GMT can be set to a different time zone and keeps track of time in two places at once using the same minute. You won’t miss your conference call in Abu Dhabi when you are in Jakarta.
