Since more than a decade, optical clocks have surpassed Cs fountains in term of accuracy and stability, making the need for a redefinition of the SI second an unavoidable step. In order to be ready for this technological change, a roadmap has been defined by the BIPM and by the CCTF, identifying a series of scientific achievement that will demonstrate the readiness of the international community. Among others the requirement of a series of frequency measurements and comparison of clocks in the E-18 region.INRIM as many other Metrological Institutes around the world, is actively participating to this effort and giving its contribution to the progressive consolidation of the optical clocks, participating in international comparison campaigns and exploiting its optical clock to calibrate TAI and to realize a time scale based on optical clocks.Authors: Filippo Levi, INRIM
