Apparatus for determining and temporarily recording the time an event occurs, comprising:
- A. a time counter,
- B. a memory,
- C. a time indicator, the time counter being coupled to the memory and the time indicator
- D. means for providing an active connection between
- a. the counter and the memory, and
- b. the counter and the time indicator, wherein the connection is arranged such that when the means for providing said connection with the memory is actuated, the time indicator indicates the time when said connection has become effective
- wherein the memory is a storage memory, the connecting means between said memory and said counter being arranged such that when said connecting means becomes operative the counter is temporarily blocked, the counting pulses are by-passed to and collected by the memory and, when the latter is fully loaded, the same number of pulses which are stored in the memory but having a frequency higher than that of the counting pulses are sent to the counter for time resetting purposes.
