The radio signal communicates the atomic time of Braunschweig to a radio tower in Mainflingen, Frankfurt. The atomic time evaluated in the PTB is called TA. Many of these caesium atomic clocks can be found in the Physikalisch-Technischen-Bundesanstalt (PTB) in Braunschweig, Germany, where the German daylight saving time is determined. 260 atomic clocks from 60 different time institutes all over the world, and then deduce the international atomic time from them. The international atomic time (TAI) is determined in the Bureau International des Poids et des Mesures (International Bureau of Weights and Measures) in Paris. The most precise time in the world today is the atomic time, based upon the International System of Units (SI) second.Įverywhere in the world there are many time institutes, which measure the atomic time through caesium atomic clocks. Since the beginning of time measurement people have been trying to measure time more and more precise.
