Atomic clocks are considered the most accurate measure of time. They use the vibrations of atoms, usually cesium or rubidium, to keep time with unprecedented precision. Cesium atomic clocks are accurate to within one second over millions of years, which makes them the standard in timekeeping for global navigation satellite systems (GNSS) and scientific research. Their reliability ensures synchronization for various technologies crucial to modern life.
