title: jQuery UI date picker - updating another date picker on selecting a date
body: <p>I have 2 date pickers using the Jquery UI. If the user selects a date from date picker 1, how can I get it to update date picker 2 automatically with the same date?</p>
  
  <p>I think this might be quite simple, but I've tried a few things and nothing seems to work.</p>
  
  <p>Thanks in advance.</p>
