The Quests' Cooldown Time is set when one picks a Quest or when one turns the Quest in ? For example, say that a Quest has a 2 hours downtime. I pick it up, say, at 8 PM. Then do the Quest at my ease, finally complete it at 11 PM (3 hours later). Can I pick the same Quest right away having passed 3 hours from 8 PM ? Or does the system look at 11 PM which is the time I turned it in for reward and sets the 2 hours cooldown from 11 PM and until 1 AM ?? Thanks.
