title: "AJAX" Calendar Widget that include Time Selection
body: <p>Are there any existing AJAX/Javascript Date picker widgets/libraries that also allow you to select a time range?  That is,  after picking a date, an existing UI pops-up/becomes available to select a time range for the same.</p>
  
  <p>I'm looking for example of things like <a href="http://jquery-week-calendar.googlecode.com/svn/trunk/jquery.weekcalendar/full_demo/weekcalendar_full_demo.html" rel="nofollow noreferrer">this</a>.  UI Libraries that offer some form of date picking, followed by a step to pick a time range.</p>
  
  <p>Yes, I know, a dozen different ways this could be implemented myself. I'm interesting in knowing what kind of preexisting libraries exist for this problem domain.</p>
