Since then, GMT is no longer a time standard. Until 1972, Greenwich Mean Time (also known as Zulu time) was the same as Universal Time (UT). UTC was adjusted several times until 1972, 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. The name Coordinated Universal Time was officially adopted in 1967. In 1960, the International Radio Consultative Committee formalized the concept of UTC, and it was put into practice the year after. The transit circle is a part of the telescope's mechanics and it is still cited as the prime meridian's original reference (0° longitude). The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London.

Universal Time (UT1): Also known as astronomical time or solar time, it refers to the Earth's rotation.International Atomic Time (TAI): A time scale that combines the output of some 400 highly precise atomic clocks worldwide, and provides the exact speed for our clocks to tick.Two components are used to determine UTC: The world's timing centers have agreed to keep their time scales closely synchronized - or coordinated - therefore the name Coordinated Universal Time.
