0 | Elapsed wall-clock time |
1 | Elapsed user time |
2 | Elapsed system time |
The user time is the time the cpu spent executing in user mode. The system time is the time spent in the system executing on behalf of the process. This uses the UNIX getrusage or times system calls, which may not be available on all systems. If support is not available, e.g., in Windows, the user and system entries will be zero, but the wall-clock time is valid. This function always returns 1.
