Abstract
The electronic chronometry device (D) comprises an acquisition cell (2) arranged to receive time data (6) coming from at least one time events measurement sensor (8), a storing unit (9) for storing said time data (6), and a processing unit (4) of said time data (6) and associated with said acquisition cell (2). This device is characterized in that said storing unit (9) is associated with an interface (1) which is arranged so as to allow said processing unit (4) to access said storing unit (9) and to read certain of said time data (6) stored in said storing unit (9) without allowing modification of said storing unit (9) by said processing unit (4).
