[AccessD] OT(kinda): Crack Code

The date is stored in the table...but not the time.  If you want a 
date/time...I have to plug the OBJID into the FE and it converts it for me.  
I can extract the date and the OBJID...but you can have up to 86400 
different OBJIDs for 1 date.  I can try to get about 100 if you like.
