When having a module set up to display the latest posts for a forum. Then Posting an announcement post with proper date and time for when it is to be displayed (like sometime in the future).  The post does not show in the forums (works properly) but if you look at the last posts module the announcement post shows up and is able to be clicked on and read before it is is suppose to be read.

This happens on AF3.5 and DNN3.2.0
