A time measurement includes a multiphase clock generator and a phase sampling circuit. The multiphase clock generator generates a sequence of a given number n of phase shifted clock phases, wherein one of the phase shifted clock phases represents a reference clock signal. The phase sampling circuit is configured to generate a phase value indicative of a number of fractions 1/n of the clock period of the clock phases elapsed between an edge of the reference clock signal and an instant when an asynchronous event signal is set. The phase sampling circuit includes first through fourth sub-circuits, which respectively generate or determine first through fourth control signals.
