title: First random number is always smaller than rest
body: <p>I happen to notice that in C++ the first random number being called with the std rand() method is most of the time significant smaller than the second one. Concerning the Qt implementation the first one is nearly always several magnitudes smaller.</p>
  
  <pre><code>qsrand(QTime::currentTime().msec());
  qDebug() &lt;&lt; "qt1: " &lt;&lt; qrand();
  qDebug() &lt;&lt; "qt2: " &lt;&lt; qrand();
  
  srand((unsigned int) time(0));
  std::cout &lt;&lt; "std1: " &lt;&lt; rand() &lt;&lt; std::endl;
  std::cout &lt;&lt; "std2: " &lt;&lt; rand() &lt;&lt; std::endl;
  </code></pre>
  
  <p>output:</p>
  
  <pre><code>qt1:  7109361
  qt2:  1375429742
  std1: 871649082
  std2: 1820164987
  </code></pre>
  
  <p>Is this intended, due to error in seeding or a bug?
  Also while the qrand() output varies strongly the first rand() output seems to change linearly with time. Just wonder why.</p>
