Time scale UTC(IT)
Laboratorio scala di tempo
The INRIM Time and Frequency Laboratory realises the reference unit of the standard time for Italy. The Italian time scale UTC(IT) is generated with an ensemble of commercial atomic frequency standards (hydrogen masers and cesium beam clocks) supported by primary frequency standards (atomic cesium fountain and ytterbium lattice clock). Synchronisation satellite systems are used for the comparison of UTC(IT) with the time scales generated by other NMI laboratories, thus contributing to the international realization of UTC by BIPM.
