  Time of Flight methods have been rapidly developed and used in many
experiments recently for determination of particle direction, identification of
particles and energy resolutions. This paper describes a method of time-mark
determination on the reconstruction algorithm, based on the sampled signal,
used for time-of-flight measurements. This method was developed for
distinguishing the signals by fitting to pulse shape which were received from
scintillator detector with a silicon photomultiplier readout have been
developed for a cosmic ray counter telescope. The method was verified using
experimental data taken in the location $40^{o}54'52"N$ and $38^{o}19'26"E$
with the elevation of 30 m above the sea level. The data samples were acquired
by the counters which have a scintillator with dimensions of
20$\times$20$\times1.4~cm^3$, optically coupled from one side to silicon
photomultiplier, then the signals readout by fast sampling digitizer board
Domino Ring Sampler Board version 4. The method can reconstruct each pulse even
for multiple events without losing the count within the small time window.
Using this method 4.969 ns time-of-flight value were established and the rise
times for scintillation counters, named Tile 1 and Tile 2, were measured about
$6.27 \pm 0.16~ns$ and $4.979\pm0.165~ns$, respectively.
