  The seeded FEL FERMI@Elettra has completed the commissioning of FEL1 line, and it is now providing the User Community with a coherent and tunable UV radiation (from 70nm to 20nm) in a number of different configurations, including an original twin-seeded pump-probe scheme. Among the key sub systems for the operation of FERMI@Elettra, there are the femto second optical timing system, some dedicated longitudinal diagnostics, specifically developed for FERMI@Elettra and, of course, state of art laser systems. In this paper, after a short review of the FERMI@Elettra optical timing system and of its routinely achieved performances, we focus on the results obtained from the suite of longitudinal diagnostics (Bunch Arrival Monitor, Electro Optical sampling station and RF deflectors) all operating in single shot and with 10s fs resolution which demonstrate the FERMI@Elettra achieved performances. The results from these longitudinal diagnostics are compared and shot to shot correlated with the results obtained from an independent longitudinal measurement technique, based on a spectrometer measurement of a linearly chirped electron bunch, which further validate the FERMI@Elettra operation.
