摘要：
An electronic entity such as a chip card containing time measurement elements includes a capacitative component (20) having a leak through the dielectric area thereof and being able to be charged when the entity is coupled to an electric power source and a member (22) for measuring the residual charge of the capacitative component which is implemented in a subsequent measure.
