Understanding UTC: The Coordinated Universal Time Standard

UTC stands for Coordinated Universal Time. It is the primary time standard by which the world regulates clocks and time. It is a modern continuation of Greenwich Mean Time (GMT), which was established in 1675.

UTC is based on the Earth's rotation and is not subject to the variations of local time zones. It is used as a reference time for scientific, technical, and legal purposes. All civil and military time around the world are now based on UTC, with each time zone being offset from UTC by a specific number of hours, minutes, and seconds.

The advantage of using UTC is that it provides a single, unified time standard that can be used globally, without the confusion of different local time zones. This has made it easier to coordinate activities across different countries and regions, and has facilitated international communication, trade, and travel.
