title: strptime in Javascript
body: <p>I have a date input field that allows the user to enter in a date and I need to validate this input (I already have server side validation), but the trick is that the format is locale dependent. I already have a system for translating the strptime format string to the the user's preference and I would like to use this same format for validating on the Javascript side.</p>
  
  <p>Any ideas or links to a <code>strptime()</code> implementation in Javascript?</p>
