title: Format LT datetimepicker : always returns today's date
body: <p>I've to use the bootstrap datetimepicker for a legacy project.</p>
  
  <p>With "LT" format, I've an issue, even if I set a default date, it returns the current date. (today).</p>
  
  <p>check it on 
  <a href="https://codepen.io/zalinn/pen/ZxbPZQ" rel="nofollow noreferrer">codepen</a></p>
  
  <pre><code>$(function () {
    $('#datetimepicker3').datetimepicker( {
      defaultDate: moment("15/05/1992","DD/MM/YYYY"),
      format: 'LT'
    });
  
    $('#datetimepicker3').on('dp.change',function(){
      console.log('-');
      console.log($('#datetimepicker3').data('DateTimePicker').date());
      console.log($('#datetimepicker3').data('DateTimePicker').date().format('DD/MM/YYYY HH:mm'));
      console.log('-');
    });
  });
  </code></pre>
  
  <p>I need to receive the date I set by default in datetimepicker.</p>
  
  <p>Thanks.</p>
