Coordinated universal time utc clock2/19/2023 Or we can measure time based on the rotation of Earth on its axis with respect to the stars (Universal Time or UT1).įinally, we can measure time through the oscillations of atoms (International Atomic Time). For instance, we can measure the passage of time via the orbital motion of Earth and other planets in the solar system (Dynamical Time). (n.d.Time can be measured in a number of ways. Next time you check your watch or glance at the clock, think about how every second has been accounted for in our world. The reading material alone is in of itself is bulkage that extends the typical mind. If you ever have some free reading time, check up on the standards of measurement on a global basis. If we knew the calculations, astronomical observations, worldwide coordination, and the international time associated groups that keep our clocks running on time, it would be more than the average person could handle! UTC was internationally implemented replacing GMT.The International Time Bureau coordinated an international/universal coordination of time/frequency which became known as UTC. Naval Observatory all agreed to coordinate time/frequency transmissions based on UT2. The Royal Observatory (Greenwich,) National Physical Laboratory England, and the U.S.UT2 – did the same thing UT1 did but used a seasonal variant to account for the Earth’s rotational speed seasonal difference. UT1 – did the same thing UT0 did but also measured the position of the pole in respect to the site that was observing it making small corrections to be able to produce a time scale. UT0 – measured the Earth’s rotational axis in respect to a site that was observing it.
