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.

Our precise algorithm takes into account various factors, such as daylight saving time and the specific offset between the two time zones, to provide you with an accurate conversion. Before the establishment of standardized time zones, local times were determined by each city's own solar noon the time when the Sun is at its highest point in the sky. However, if you prefer a hassle-free way to find the time in another part of the world, feel free to use our Time Zone Conversion Calculator on the directory page. It doesn't have any associated cities, as it serves as the basis for calculating time differences between different time zones. Greenwich Mean Time GMT is the time zone used as the basis for calculating time differences worldwide. It is the same as Coordinated Universal Time UTC and has no associated cities, as it serves as a reference point for all other time zones. Exactly What Is Time. Calculate the offset : Find the difference in hours and sometimes minutes between the two time zones. Consider daylight saving time : Check if either the starting or destination time zone is currently observing daylight saving time. If so, make sure to adjust your calculation by adding or subtracting one hour as needed. Apply the offset : Add or subtract the calculated offset to the given time in the starting time zone am.

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.

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.
