title: combine date and time into a single datetime
body: <p>I have a date and time control, which I would like to concatenate</p>
  
  <pre><code>var startDate = jQuery('#startDatepicker').find("input").val();
  var startTime = jQuery('#startTimepicker').find("input").val(); 
  </code></pre>
  
  <p>I have another var field which has data as below:</p>
  
  <pre><code>var targetTime = new Date().setMinutes(-5).valueOf(); 
  </code></pre>
  
  <p>startDatepicker has the value as : 02/06/2017</p>
  
  <p>startTimepicker, currentTime has the value as : 05:17 am</p>
  
  <p>targetTime has the value as: 1486374940591</p>
  
  <p>I want to concatenate startdate and starttime in the format of targetTime. How to concatenate the start date and start time?
  Thanks</p>
