title: clock_t does not work on Linux?
body: <p>This is what I have been using in WIndows:</p>
  
  <pre><code>#include &lt;ctime&gt;
  #include &lt;iostream&gt;
  
  int main( void )
  {
      using namespace std;
  
      clock_t lastT;
      lastT = clock();
  
      cin.get();
      cin.get();
      return 0;
  }
  </code></pre>
  
  <p>In Linux I get the error:</p>
  
  <pre><code>'clock_t' was not declared in this scope
  </code></pre>
  
  <p>Is there some other data type for this in Linux?</p>
  
  <p>I am compiling it in Anjuta IDE by clicking Run.</p>
