title: datetimepicker sets date to todays date on when clicking outside
body: <p>I have searched high and low for the answer to this issue, but no luck so now I have to ask...</p>
  
  <p>I have the datetimepicker from Trent Richardson, and for some reason with very minimal options set, it automatically sets the date field to todays date when i click outside without selecting a date.</p>
  
  <p>Anyone have an idea whats going on?</p>
  
  <p>This is my code:</p>
  
  <pre><code>$('input.datetime').datetimepicker({
          ampm: true,
          timeFormat: 'hh:mm tt',
          addSliderAccess: true,
          sliderAccessArgs: { touchonly: false },
       });
  </code></pre>
  
  <p>Appreciate all the help I can get, its causing some confusion for my staff using the application...</p>
