With respect to its timing system, FERMI is the first "copper free" FEL facility. Having been conceived during the FERMI Technical Optimization Study (TOS), the FERMI timing system is based on the original ideas developed at MIT/DESY and at LBNL, which have been demonstrated also with the significant support of Sincrotrone Trieste. Since then, at FERMI, a young though strong team has been growing in time, now running the system on the facility. As for the trigger distribution we have adopted the COTS solution by Micro-Research Finland Oy, the main original contribution to the Community is found in the phase reference generation and distribution. The huge engineering effort afforded by the FERMI project in the last twelve months has produced a unique system that is now ready to assure a stable seeded FEL operation. The final system implementation is presented here along with the obtained performances, at the few tens of fs level (jitter and drifts).
