title: datepicker parsing date issue
body: <p>I've the next problem:
  when I recieve date from server, I want to format it via datepicker, but datepicker throws exceptions, cause it can't parse the date.
  here is my date, whcih comes from server(obj.value):
  <code>08.20.2012 19:01:32</code>
  and here is code via which I try to parse this date:
  <code>$.datepicker.formatDate('dd.MM.yy', new Date(obj.value));</code>
  I use MM cause I need the full name of the month.
  and here is output after parsing:
  <code>NaN.NaN.NaN</code>
  so how to get rid of this exception?</p>
