Dungeon timer

Hey guys,

I want to create a plugin that keeps track how long an instance clearing run has taken and if it is longer than X amount of time to wait before resetting.
Any help or pointers would be appreciated! I'm using dungeonbuddy to farm instances but unfortunately sometimes the run takes less than 6 minutes and the bot repeatedly tries to enter the instance (that's where blizzard moves in to ban :D).

Thanks!
