title: Server side timer after meteor collection is updated
body: <p>I'm currently developping a simple realtime multiplayer game and i'm stuck with the timer logic.</p>
  
  <p>When there are enough players in a game, the status of the game is set to "STARTED" and from there i want to start a 10 seconds timer and show it to all the clients.</p>
  
  <p>My idea is to use collection hooks and call a setTimeout after the collection update. But I don't really know how to do it and if it is the best solution.</p>
  
  <p>Also maybe should I use cron instead of timers? </p>
