Current time greenwich mean time
At different times in the past, it has been calculated in different ways, current time greenwich mean time, 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 tiltnoon GMT is rarely the exact moment the Sun crosses current time greenwich mean time 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.

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. Funnily enough, while time zones are technically strictly defined by geography, it can sometimes be a purely political decision. For example, India spans a vast territory with several time zones in the geographical sense, but ever since the colonial era, the country observes only one single time zone from border to border. After all, this is precisely what GMT is: an agreement. Introduced to help with naval navigation when travelling around the world, GMT was once the international civil time standard.

The Time Now is a reliable tool when traveling, calling or researching. One of the best place to start with is Greenwich Mean Time. Humans have pursued an accurate way of telling time since the dawn of our history. We have always looked to the stars for answers to these questions. The solstices and equinoxes provided points of reference for us to use in our pursuit. The sun was always due east at 6 AM, above your head at noon, and in the west at 6 PM. The Royal Greenwich Observatory started the process for a unified standard time by becoming the Prime Meridian or the zero longitude for the world. GMT is known as the global time standard. GMT is a term also used by the countries of the commonwealth which include the following locations:. There are of course other countries in the Eastern Hemisphere that also use the term.

Although that instrument still survives in working order, it is no longer in use and now the meridian of origin of the world's longitude and time is not strictly defined in material form but from a statistical solution resulting from observations of all time-determination stations which the BIPM takes into account when co-ordinating the world's time signals.
