Home » Astronomy » Time. It differs from solar or astronomical time clock time because solar time varies throughout the year.

Weather observations around the world including surface, radar, and other observations are always taken with respect to a standard time. It is also known as "Z time" or "Zulu Time". To obtain your local time here in the United States, you need to subtract a certain number of hours from UTC depending on how many time zones you are away from Greenwich England. The table below shows the standard difference from UTC time to local time. The switch to daylight saving time does not affect UTC. It refers to time on the zero or Greenwich meridian, which is not adjusted to reflect changes either to or from Daylight Saving Time. However, you need to know what happens during daylight saving time in the United States.

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. As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of Synchronisation of the chronometer on GMT did not affect shipboard time, which was still solar time. But this practice, combined with mariners from other nations drawing from Nevil Maskelyne 's method of lunar distances based on observations at Greenwich, led to GMT being used worldwide as a standard time independent of location. Greenwich Mean Time was adopted across the island of Great Britain by the Railway Clearing House in and by almost all railway companies by the following year, from which the term railway time is derived. It was gradually adopted for other purposes, but a legal case in held " local mean time " to be the official time. For example, our polling booths were opened, say, at 8 13 and closed at 4 13 p. Universal Time UT , a term introduced in , initially represented mean time at Greenwich determined in the traditional way to accord with the originally defined universal day ; from 1 January as decided by the International Astronomical Union in Dublin in , at the initiative of William Markowitz this "raw" form of UT was re-labelled UT0 and effectively superseded by refined forms UT1 UT0 equalised for the effects of polar wandering [16] and UT2 UT1 further equalised for annual seasonal variations in Earth rotation rate.

By Anne Buckle and Vigdis Hocken. In November , the General Conference on Weights and Measures CGPM —an international body that decides on global standards for how things are measured—passed a resolution asking the International Telecommunication Union ITU to consider changing the way we define civil time. Read the full story. UTC is the time standard commonly used across the world. The world's timing centers have agreed to keep their time scales closely synchronized - or coordinated - therefore the name Coordinated Universal Time. This is the basis for the hour time zone system we know today. The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London. The name Coordinated Universal Time was officially adopted in UTC was adjusted several times until , when leap seconds were introduced to keep UTC in line with the Earth's rotation, which is not entirely even, and less exact than atomic clocks. Since then, GMT is no longer a time standard.

With the globalisation and evolution of international relationships, the need for universal time identification has occurred. Especially, it was vital to have a standardised time zone for communication and military coordinations. Therefore, the difference in time for other countries is indicated either by adding or subtracting hours from GMT time. The primary difference remains to be the fact that GMT is the denomination of a timezone, while UTC is the title of the time standard. The advancement of telecommunication technologies influenced the creation of an even more precise system of time identification. In particular, the concept of Coordinated Universal Time UTC was designed to provide a more accurate timekeeping system. Nevertheless, both of these time standards are widely used in the world for a similar purpose of time coordination.
