| .SH DESCRIPTION |
| Both |
| .I time |
| and |
| .I nsec |
| return the time since the epoch 00:00:00 GMT, Jan. 1, 1970. |
| The return value of the former is in seconds and the latter in nanoseconds. |
| For |
| .IR time , |
| if |
| .I tp |
| is not zero then |
| .BI * tp |
| is also set to the answer. |
| .PP |
| These functions work by reading |
| .BR /dev/bintime , |
| opening that file when |
| .I they |
| are first called. |
