I don&#39;t know why but the boost::timer does work well.<br>Please, look at the following example bellow and if any idea let me know.<br><br>#include &lt;boost/timer.hpp&gt;<br>#include &lt;iostream&gt;<br>#include &lt;unistd.h
&gt;<br><br>int main()<br>{&nbsp;&nbsp;  <br>&nbsp;&nbsp;&nbsp; boost::timer timer;<br><br>&nbsp;&nbsp;&nbsp; sleep(1);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* block until one second has elapsed */<br>&nbsp;&nbsp;&nbsp; std::cout &lt;&lt; timer.elapsed
() &lt;&lt; std::endl;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; /* show the elapsed time (one second expected) */<br>&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; return 0;<br>}<br><br>Though I am not sure I thing the timer just have in mind the time the processor was busy and not the time the application was running.
<br>Has the boost library any standard sleep(), I have heard boost::asio has a very good one.<br><br>Thanks in advance.<br><br>
