TAI (International Atomic Time)

International Atomic Time (TAI) is a time standard that measures time based on atomic clocks, which are extremely accurate. Established in 1958, TAI counts the seconds since a specific date (January 1, 1958) and is maintained by a network of atomic clocks around the world. Unlike other time measurements that might rely on the Earth's rotation, TAI provides a consistent and precise measure of time, ensuring synchronization for scientific purposes, navigation, and telecommunications. It serves as the foundation for Coordinated Universal Time (UTC), which includes adjustments to account for Earth's rotation.
