Actually, why wouldn't Quantus's time magic be resisted? It's magic that slows down or freezes time, which isn't a magic that is wholly destructive, so...nani sore? The concept behind Legendary Resistance is that Arata can only be slowed or stopped through a violent, destructive force, and I'm pretty sure that slowing down time wouldn't actually hurt at all.
