| <dt><em>Description</em>:</dt> |
| <dd><p>Returns the current time encoded as an integer (in the manner of the |
| function <code>time(3)</code> in the C standard library). This value is |
| suitable for passing to <code>CTIME</code>, <code>GMTIME</code>, and <code>LTIME</code>. |
| </p> |
| <p><em>Warning:</em> this intrinsic does not increase the range of the timing |
| values over that returned by <code>time(3)</code>. On a system with a 32-bit |
| <code>time(3)</code>, <code>TIME8</code> will return a 32-bit value, even though |
| it is converted to a 64-bit <code>INTEGER(8)</code> value. That means |
| overflows of the 32-bit value can still occur. Therefore, the values |
| returned by this intrinsic might be or become negative or numerically |
| less than previous values during a single run of the compiled program. |
