What is gmt time zone now

Weather observations around the world including surface, radar, and other observations are always taken with respect to a standard 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. To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight.

Legally, the civil time used in the UK is called "Greenwich mean time" without capitalisationwith an exception made for those periods when the Summer Time Act orders an hour's shift for daylight saving. The term GMT should thus not be used for purposes that require precision.

A time zone is a region on Earth that uses a uniform time. They are often based on the boundaries of countries or lines of longitude. Although GMT used to be a time standard, it is now mainly used as the time zone for certain countries in Africa and Western Europe.

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.
