Abstract Plain Text: 

Particle identification is an important feature of the ALICE detector at the LHC. In particular, for particle identification via the time-of-flight technique, the precise determination of the event collision time represents an important ingredient of the analysis. In this paper, the different methods used for such a measurement in ALICE by means of the T0 and TOF detectors are reviewed. Efficiencies, resolution and consequent improvement on the particle identification separation power of the methods used are presented for the different LHC colliding systems (pp, p-Pb and Pb-Pb) during the first period of data taking of LHC (RUN1).
