A device for generating a characteristic time, which is built in a computer as shown in the figure by way of example. The computer includes a CPU (1), a memory (2) and an input/output device (3). The CPU (1) is provided with clock (4) and a counter (5). The memory (2) includes a section (6) for storing a period of elapsed time and a section (7) for updating a period of elapsed time. The section (6) for storing a period of elapsed time stores the total amount of time to be counted, for example, 3,155,692,500.97 sec (in 1/100 sec steps) corresponding to 100 years, as a total time Tt. The clock (4) is associated with a section for constantly counting the total time Tt, and the counter (5) calculates the cumulative time Tn from 0 to the total time Tt and the differential time (Tt - Tn) required to count down from the total time Tt to 0, thereby constantly counting elapsed time. The elapsed time counted by the device for generating a characteristic time can be outputted to another computer by the input/output device (3), whereas the elapsed time counted by another computer can also be inputted by the input/output device (3).
