Not sure if the ability to place timed events will exist in DOM_3, but at least the devs saw the idea.  
  
 Being able to setup unique events for nations and/or provinces can make a map more interesting... such as earthquakes, volcanoes, floods and/or  creating a storyline for gamers to experience.
example: 
    Event:  Give ERMOR 
    Commander: Demon Knight
    Items: Marble Armor; Amulet of Antimagic 
    Units: 30 Demon Knights 
    Guards: 2 Devils
    Province: Ermor Capital 
    Day:  58
    
post message to human players: 
     "Ermor has recalled his greatest knights from a distant land to remove his enemies from this realm."
