Abstract
A time management system that includes a first clock having a first counter operating on a first timebase, a second clock having a second counter operating on a second timebase identical to the first timebase and a third counter operating on a third timebase less than the second timebase. The time management system performs a resynchronization of the second clock after the main electrical power supply has been restored, this resynchronization including, on a modification of the first counter, loading the first counter into the second counter and in zeroing the third counter.
