Method and system for synchronizing a plurality of pieces of equipment, wherein it includes at least the following steps: in each equipment generating the command signal, computing a value of the difference ΔH between a reference-clock value Hm and the local clock Hi of an equipment, on detecting a phase shift ΔH between the reference-clock value and the value of a local clock, when the value of the phase shift ΔH between the local clock and the reference clock corresponds to one refresh cycle of the reference clock Hm, a corrected clock time Hic is defined by repeating a number of the clock signal of given parity if the value of the local clock is early and a corrected clock time is defined by skipping one number of the clock signal of opposite parity to the first parity if the local clock value is late, when the value of the phase shift ΔH is higher than one refresh cycle, the method resets the reference time, a corrected value of the clock in each equipment is used to emit the command signal.
