(57) The invention relates to a system (10) for controlling and/or recording and/or indicating
of elapsed time and/or of events following one another in the time. The system (10)
comprises a unit (10) suitable for receiving and recording data coming from a first
suitable carrier (12), for processing said data and for presenting them in a displayed
and/or recorded form on a second suitable carrier (16), said unit (10) comprising
at least one reading device (14, 15) for reading the data recorded on said first carrier
(12), a clock circuit giving a signal of elapsed time. According to the invention,
the system comprises an electronic circuit suitable for processing the data detected
on said first carrier, for associating them to the signals coming from said clock
circuit and to record them on said second carrier (16), and in that said unit (10)
is completely autonomous and fed by a suitable battery.
