ISTR that timed missions are second only to escort quests in terms of being one of the most universally disliked game features; that may be apocryphal but it's something that I certainly find myself agreeing with. Choices and consequences are one thing, but I put enough effort into not being late IRL, I don't want my escapism to make a point of it too!
Agree, timed quests are not great and are especially tricky/annoying to do in games that have a world clock built into them. Plus all it really leads to is players reloading and trying the "race" again.
