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

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.

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". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight.
