(54)	Stop watch and clocking system

(57) The stop watch comprises a magnetic sensor (2) for sensing magnetism and generating a signal upon detecting a predetermined amount of magnetism, a clocking section (1) for controlling the start and end of clocking each time the signal is received and storing a measured time, and a display section (3) for displaying the time stored in the clocking section (1). The magnetic sensor (2) is installed in an automobile and connected to the clocking section (1) via a cable, and the clocking section (1) and the display section (3) are formed integrally. Magnetic members (50, 51, 52) are installed in a course (40) on which the automobile (41, 42) travels.
