Jul 31, 2023 · Coordinated Universal Time (UTC) is the worldwide reference time scale computed by the Bureau international des poids et mesures ( BIPM) − the international organization dealing with matters related to measurement science and measurement standards.
The recommended maximum departure of UTC from UT1 was 0.7 s. The term “leap second” was introduced for the stepped second. An additional correction DUT1 was introduced, having integral multiples of 0.1 s, to be embodied in the time signals such that, when added to UTC, they would yield a better approximation to UT1.
Coordinated Universal Time ( UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce.
Coordinated universal time (UTC) UTC is the time-scale maintained by the BIPM, with assistance from the IERS, which forms the basis of a coordinated dissemination of standard frequencies and time signals. It corresponds exactly in rate with TAI but differs from it by an integer number of seconds.
Aug 23, 2023 · BIPM is responsible for the definition and publication of the reference time scale UTC in accordance with Resolution 2 of the 26th CGPM, held in 2018; CGPM will determine the timeline and a future limit on the quantity UT1‑UTC, as laid down in Resolution 4 of the 27th CGPM in 2022; and.
