"Wall clock time" is just another way of saying "elapsed time" (you measure elapsed time with the clock on the wall, yes?)


"I come to the conclusion that, men loving according to their own will and fearing according to that of the prince, a wise prince should establish himself on that which is in his own control and not in that of others." -- Niccolò Machiavelli

And CPU time is the amount of time the CPU spent on YOUR job.
