INRiM provides the Italian Standard Time, realized from the atomic clocks in our laboratories.

This signal derives from the realization of UTC(IT), the Italian time scale, which is also used by the Bureau international des poids et mesures (BIPM) to realize the international time scale, UTC (Universal Time Coordinated).

INRiM provides the Italian standard time through its NTP servers (Network Time Protocol), which are freely available to users.
