title: Converting a 2 digit year to a 4 digit one
body: <p>We have an entry form that gives the user a calendar drop down, but also are allowed to type in a data manually. We discovered that if a person enters a 2-digit year, the year is changed to 1912 not 2012 (dates cannot be in the past). Is there a way I can:</p>
  
  <ol>
  <li>Check if they entered a 2-digit year and convert that to a 4-digit year, or</li>
  <li>Give them an error if they enter a 2-digit year.</li>
  </ol>
  
  <p>This is on an HTML form and I also am using jQuery for a bunch of other stuff.</p>
  
  <p>I should clarify that they enter the date as a whole date 01/01/2012 or 1/1/2012 is valid. 1/1/12 and 01/01/12 is not.</p>
