• wall time: n. (also `wall clock time') 1. `Real world' time (what the clock on the wall shows), as opposed to the system clock's idea of time.
  2. The real running time of a program, as opposed to the number of {tick}s required to execute it (on a timesharing system these always differ, as no one program gets all the ticks, and on multiprocessor systems with good thread support one may get more processor time than real time)....
• clocks: n. Processor logic cycles, so called because each generally corresponds to one clock pulse in the processor's timing.
  The relative execution times of instructions on a machine are usually discussed in clocks rather than absolute fractions of a second...
