| Knowing how long a program takes to execute is useful in both test and |
| production environments. It is also helpful if such timing information |
| is broken down into real (wall clock) time, CPU time spent by the user, |
| and CPU time spent by the operating system servicing user requests. |
| </p> |
| <p> |
| Process clocks don't include the time spent by the child process. |
