<h3 class="section">8.4 <code>difftime</code>—subtract two times</h3>
<a name="index-difftime"></a>
<p><strong>Synopsis</strong>
</p><div class="example">
<pre class="example">#include <time.h>
double difftime(time_t <var>tim1</var>, time_t <var>tim2</var>);
</pre></div>
<p><strong>Description</strong><br>
Subtracts the two times in the arguments: ‘<code><var>tim1</var> - <var>tim2</var></code>’.
</p>
<br>
<p><strong>Returns</strong><br>
The difference (in seconds) between <var>tim2</var> and <var>tim1</var>, as a <code>double</code>.
</p>
<br>
<p><strong>Portability</strong><br>
ANSI C requires <code>difftime</code>, and defines its result to be in seconds
in all implementations.
</p>
<p><code>difftime</code> requires no supporting OS subroutines.
