| 15 | .SH DESCRIPTION |
| 16 | Both |
| 17 | .I time |
| 18 | and |
| 19 | .I nsec |
| 20 | return the time since the epoch 00:00:00 GMT, Jan. 1, 1970. |
| 21 | The return value of the former is in seconds and the latter in nanoseconds. |
| 22 | For |
| 23 | .IR time , |
| 24 | if |
| 25 | .I tp |
| 26 | is not zero then |
| 27 | .BI * tp |
| 28 | is also set to the answer. |

| 35 | To avoid name conflicts with the underlying system, |
| 36 | .I time |
| 37 | and |
| 38 | .I nsec |
| 39 | are preprocessor macros defined as |
| 40 | .I p9time |
| 41 | and |
| 42 | .IR p9nsec ; |
