title: Overloading DateTimeShortcuts.js in Django
body: <p>Simple question really, is there any programmatic way to over load the "choose a time" options in django for the DateTimeShortcuts.js when used in the admin?  </p>
  
  <p>The options they present aren't very helpful the last option of the day is noon.  I was hoping to have every hour of the day as an option</p>
