7.23 the CPU time is time-dependent!

Yes it is! On most machines and on most operating systems, depending on machine load, on communication load (for parallel machines), on various other factors (including maybe the phase of the moon), reported CPU times may vary quite a lot for the same job. Also note that what is printed is supposed to be the CPU time per process, but with some compilers it is actually the wall time.
