An electronic device comprising a clock, means pulsed by the clock to effect a primary chronometry (CHR1) of an event from a nearby clock cycle , logic means controlled to produce a timing pulse the start of which coincide s with the event and the finish of which occurs at the R'th impulse of the clo ck after the start, a constant time circuit comprising a filter (FPB) of chosen characteristics arranged to receive the timing pulse, to generate in respons e an electrical signal having a duration greatly superior to that of the timing pulse, and means suitable for operating on a chosen portion of the response to the filt er for measuring a physical value relative to the electrical signal and representative of the duration of the timing pulse so as to enable thereby a fine chronometry of the event.
