  11 Description:
  12   Elapsed wall clock time in seconds.  The time is measured per thread, no
  13   guarantee can be made that two distinct threads measure the same time.
  14   Time is measured from some "time in the past", which is an arbitrary time
  15   guaranteed not to change during the execution of the program.
