title: Bootstrap datetimepicker display current date and allow to pick past dates
body: <p>I'm actually having some issue trying to display the current day and allowing pick past dates. If I set the current date as today's date, I can't pick past dates and if I remove the parameter <code>startDate: new Date()</code> I can pick past dates but the default displayed date change to year 1899. I can't keep both logic.</p>
  
  <p>With the following code snippet I can display the current date by default but I can not pick past dates:</p>
  
  <pre><code>             $(".form_datetime").datetimepicker({
                   format: "mm/dd/yyyy HH:ii P",
                   autoclose: true,
                   showMeridian: true,
                   startDate: new Date(),
                   todayBtn: true,
                   minuteStep: 5,
                   language: 'en',
                   forceParse: false
               });
  </code></pre>
  
  <p>So like I said, if I remove the parameter startDate, I can pick past dates but my default displayed date goes to 1899 instead of current date:</p>
  
  <pre><code>             $(".form_datetime").datetimepicker({
                   format: "mm/dd/yyyy HH:ii P",
                   autoclose: true,
                   showMeridian: true,
                   //startDate: new Date(),
                   todayBtn: true,
                   minuteStep: 5,
                   language: 'en',
                   forceParse: false
               });
  </code></pre>
  
  <p>How can I keep both things: pick past dates and show current date by default?
  I also tried adding a new function like this but it's not working neither:</p>
  
  <pre><code>             $(".form_datetime").datetimepicker({
                   format: "mm/dd/yyyy HH:ii P",
                   autoclose: true,
                   showMeridian: true,
                   //startDate: new Date(),
                   todayBtn: true,
                   minuteStep: 5,
                   language: 'en',
                   forceParse: false
               }).on('dp.show', function () {
                   return $(this).data('DateTimePicker').defaultDate(new Date());
               });
  </code></pre>
