The time shown on this site is set by an atomic clock via the NTP protocol. Currently synchronized with the Paris Observatory, France.
International atomic time is a time scale based on the definition of the second using atomic clocks. It allows to define the time standard used everywhere in the world. The second was defined in 1967 at the 13th General Conference of Weights and Measures as being the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium atom. 133. On the site HEURE-EXACTE.EU you therefore have the exact atomic time, to the nearest thousandth of a second!
