I'm sure this is the most noobish question here but, how does time pass in within the game? For example if someone is donning armour for 2 minutes, the rest of the party doesn't just sit there staring at a clock right? Same with a wizard sleeping for 8 hours, does the GM just keep track of in-game time and tell it as part of the story ie "your party sleeps for the night, the the next morning while the wizard's reading for an hour you can go buy supplies etc."?
