Elapsed processing time since the last call of ::count_seconds.
The operator ::count_seconds helps to measure the runtime. The first call of the procedure normally returns a zero. Each further call returns the processing time which has elapsed in the meantime in seconds. The C-function "clock'" is used for the measurement.
The time measurement is not exact and depends on the load of the computer.
