A METHOD FOR MEASURING THE ACCURACY OF TIMEPIECES, IN WHICH A NUMBER OF CYCLES OF A STANDARD FREQUENCY ALTERNATING SIGNAL COUNTED BETWEEN A TICK INITIATING THE MEASURING PROCESS AND A LATER TICK TERMINATING THE MEASURING PROCESS IS USED AS A VALUE FOR MEASURING THE ACCURACY OF THE TIME-PIECE, IN WHICH AFTER THE INITIATING TICK THERE IS A WAITING TIME WHICH IS INDEPENDENT OF THE SUBSEQUENT TICKS, IN WHICH THE FIRST TICK AFTER THE END OF THE WAITING TIME TERMINATES THE COUNTING OF THE CYCLES OF SAID STANDARD FREQUENCY SIGNAL, AND IN WHICH SAID FIRST TICK AFTER THE END OF SAID WAITING TIME IS AN EVEN-NUMBERED TICK, THE TICK INITIATING SAID COUNTING OF THE STANDARD FREQUENCY CYCLES COUNTING AS THE ZERO-NUMBERED TICK.
