The main task of this work is to find a fast and robust way to determine pp-collision time at the SPD experiment. Using physics motivations, from the input flux of reconstructed particles’ tracks we identify a subset of pions which is used to calculate the unbiased estimation of the event collision time. The uncertainty of the estimation is about 30 ps. This method is fast (less than 300 ns per event) and reliable, thus it will allow to process the high flux of input events at the SPD experiment.
