In this example the -5h refers to gmt hours time zone being five hours behind UTC or GMT and so forth for the other time zones. The usage of UTC and GMT is based upon a twenty four hour clock, similar to military time, gmt hours, and is based upon the 0 degrees longitude meridian, referred to as the Greenwich meridian in Greenwich, England. Coordinated Universal Time is based on cesium-beam atomic clocks, with leap seconds added to match earth-motion time, gmt hours, where as Greenwich Mean Time is based upon the Earth's rotation and celestial measurements.

What are the characteristics of a GMT watch? How do you set the second or third time zones on the different types of GMT watches and how do you read the times? All these questions will be answered in this article. This refers to the time zone division that representatives from 25 nations agreed on in at the so-called International Meridian Conference in Washington as a reference for world time. Until then, each country and sometimes even individual regions had their own time, which was based on the highest position of the sun and announced by the respective church towers or station clocks. This worked quite well until technical progress, especially in the field of railroad traffic and telegraphy, led to the desire for a uniform time or uniform time zones. The solution was to introduce a worldwide standard time to which everyone could orient themselves.

Midday in Hawaii will occur at a different time than in Moscow precisely because of the rotation of the Earth, so to make sense of time around the world and to calculate what time is it where, time zones were introduced. This happened in the late nineteenth century when a Scottish-Canadian engineer and inventor Sandford Fleming proposed dividing the Earth into 24 slices of 15 degrees each. However, this does not mean that all countries in the GMT time zone have the same hour. That is, a time zone will cover the same countries vertically, which is why the UK and South Africa observe the same time. Once again, this has to do with the rotation of the Earth: noon is noon from North to South, because the poles do not move; West to East, however, sees a difference as the Earth turns around its own axis.

At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time".

As the names of the two GMT watch types and also the descriptions already suggest, the Office-GMT is better suited if you want to display the time of another time zone with the GMT hand and the Traveller-GMT is better suited if you are traveling and want to keep an eye on your home time with the GMT hand.
