title: Not able to set older date then current if minDate property is set to moment() using Bootstrap Datetimepicker
body: <p>My requirement is i don't want allow user to select past date from the date picker (this was done using <code>minDate: moment()</code>). But i must have to show the past date in textbox as well as in datepicker dropdown.</p>
  
  <p>For example, Today is 23 Oct 2017, So i am able to select any date from today and future. But few dates that were already in past (i.e. 03 Mar 2017, 12 Nov 2016) in that case <strong>those dates were not shown in the textbox it was automatically cleared due to</strong> <code>minDate: moment()</code> <strong>feature is set. If i remove this property then i am able to show that date</strong>.</p>
  
  <p>This issue i was facing after <strong>migrating Bootstrap Version 3.0.0 to 4.17.42</strong>.
  Following is the code:</p>
  
  <pre><code>$('#datepicker').datetimepicker({
          format: 'YYYY/MM/DD',
          ignoreReadonly: true,
          defaultDate: moment(GetCurrentDate(), "DD-MM-YYYY"),
          minDate: moment()           //set a minimum date
  });
  </code></pre>
  
  <p>Using this DateTimePicker: <a href="http://eonasdan.github.io/bootstrap-datetimepicker/" rel="nofollow noreferrer">http://eonasdan.github.io/bootstrap-datetimepicker/</a></p>
