A system for managing time-stamped events with uncertain events-sequence signalling, including a list of variables of which a change of value must lead to the detection of an event to be time-stamped and to be saved; means, for each variable, for positioning a marker indicating the quality of the time-stamping of said event; a buffer for the storage, before they are read by client software, of said events to be time-stamped and to be saved, associated respectively with a time-stamping time, said time-stamped events read by the client software being erased from the buffer; means for enabling and for disabling means for saving in a history the values of the variables corresponding to said time-stamped events that have been read.

System for managing buffers of time-stamped events

The present invention relates to a method for managing the restarting of automatic control equipment, consisting in:

System and method for managing the restarting of automatic control equipment

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.
