UTC(NIST)
UTC(NIST) is the official time standard maintained by the National Institute of Standards and Technology in the United States. It is a highly precise clock that synchronizes with international time standards, serving as the basis for Coordinated Universal Time (UTC). This standard ensures uniform timekeeping across various systems and fields, such as telecommunications, navigation, and scientific research. UTC(NIST) combines an ensemble of atomic clocks to provide an extremely accurate and stable time reference, which is then used globally for time dissemination and synchronization.
