ThreadList QuertOverrides not working

Hi all,

I'm working on a custom widget which displays recent posts from all groups and forums. (Something similar to the Forum - Thread List widget)

I use sort-by LastPost and sort-order Desc, but the sorting doesn't look right. It actually sorts by last post date, but in a time frame of 24 or more hours it gives me the wrong order.

If I'm not clear enough please see following order:

2-6-2012 7:51 PM

2-6-2012 5:25 PM

2-5-2012 1:30 PM

2-7-2012 5:55 AM

2-7-2012 5:35 AM

2-7-2012 5:26 AM

2-7-2012 5:20 AM

2-7-2012 5:19 AM

2-6-2012 9:28 PM

                               <div class="post-date">

                                   <CSForum:ThreadData Property="ThreadDate" runat="server" IncludeTimeInDate="true" Tag="Span" CssClass="value" FormatString="M-d-yyyy h:mm tt" />

                               </div>

                           </ContentTemplate>

                       </CSControl:PlaceHolder>

           </td>

           </tr>

Any suggestion why the sorting is not working would be appreciated.

Thanks
