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).
