WebUTC is generated at the BIPM by use of a post-processed time-scale algorithm and is not available in real -time. The parameters that we use to generate UTC(NIST) in real -time are therefore based on an extrapolation of UTC from the most recent available data. UTC(NIST) is generated as an offset from our real-time scale AT1. Time steps are never ... Weband we consequently propose an updated computation of TT(BIPM). We use all recently available data from new Cs fountain PFS and a revised estimation of the stability of the free atomic time scale EAL on which TAI is based. The performance of the new realization of TT is discussed and is used to assess the accuracy of recent PFS measurements. 1.
