| * This tests: |

| * - whether pj_gettimeofday() works. |
| * - whether pj_get_timestamp() and friends works. |
| * |
| * API tested: |
| * - pj_thread_sleep() |
| * - pj_gettimeofday() |
| * - PJ_TIME_VAL_SUB() |
| * - PJ_TIME_VAL_LTE() |
| * - pj_get_timestamp() |

| * - pj_elapsed_time() |
| * - pj_elapsed_usec() |
