This value is suitable for passing to <code>CTIME</code>, <code>GMTIME</code>, and <code>LTIME</code>. <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. <br><dt><em>Standard</em>:<dd>GNU extension <br><dt><em>Class</em>:<dd>Function <br><dt><em>Syntax</em>:<dd><code>RESULT = TIME8()</code> <br><dt><em>Return value</em>:<dd>The return value is a scalar of type <code>INTEGER(8)</code>. <br><dt><em>See also</em>:<dd><a href="CTIME.html#CTIME">CTIME</a>, <a href="GMTIME.html#GMTIME">GMTIME</a>, <a href="LTIME.html#LTIME">LTIME</a>, <a href="MCLOCK8.html#MCLOCK8">MCLOCK8</a>, <a href="TIME.html#TIME">TIME</a> </dl> </body></html>
