| contents | This study outlines the progress of a collaborative effort between INRIM and MUOGRAPHIX-The University of Tokyo, focusing on using muons from cosmic-ray-induced Extensive Air Showers (EAS) to synchronize atomic clocks and disseminate atomic time references. The approach, known as the Cosmic Time Synchronizer (CTS), proposed by the University of Tokyo, serves as the foundation for a new field of study called Muochrony. The paper details the CTS technology, underlying principles, and the prototype system installed at the INRIM RadioNavigation Laboratory. Additionally, it reports on the initial metrological evaluation and the first experiments conducted to synchronize diverse atomic clock types and disseminate the UTC(IT) timescale using cosmic muons. CTS has the potential to synchronize and disseminate time references in critical applications securely and could also complement GNSS in areas not covered by RF signals. |
