Time in gmt+1

At different times in the past, it has been calculated in different ways, time in gmt+1, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given.

Spain has two time zones and observes daylight saving time. However, the time zone was changed to Central European Time in and has remained so since then, meaning that Spain does not use its "natural" time zone under the coordinated time zone system. Some observers believe that this time zone shift plays a role in the country's relatively unusual daily schedule late meals and sleep times. Spain, like other parts of the world , used mean solar time until 31 December Before 1 March , the Canary Islands still used mean solar time until it was discovered that the royal decree of applied only to the Peninsula and Balearic Islands. It is very popular in Spanish national media, mainly on the radio and television , to list the notice " una hora menos en Canarias " English: "one hour less in the Canary Islands" [3] when the local time is mentioned. It was then introduced and abolished several times.

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. The term GMT should thus not be used for purposes that require precision.

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.
