title: Angular ui date picker short date format, incorrect past date/year after selection
body: <p>UI date picker is showing incorrect date when, short date is selected from the format and any date in previous years like 1921 is selected, the date selected will be shown as in year 2021, ideally it should be shown as 1921.</p>
  
  <p>Below is the official implementation, where it can be checked.

  <p>Steps to reproduce.</p>
  
  <ol>
  <li>Change Format dropdown to shortDate.</li>
  <li>Select date as in year 1921 or 1962 etc.</li>
  <li>The selected date year would be 2021 or 2062.</li>
  </ol>
  
  <p>Does anyone has any idea about this. Is this a bug in plugin?</p>
