action framework format date

Irvin is on the right track.  Either make a formula field that reworks the date into component pieces and rearranges them as you want. 
or use some quick javascript to put together the information that needs to go into the display.  This will probably most easily be created using our “Custom component” 

Here are a few resources for the coding: 

Adjusting Date Format in custom field renderer. 

Using custom component to show text plus some calculated data.  (Start with step 6 of this tutorial)

You should be able to do this pretty quickly.
