There aren't very many Time-elemental attacks in the game, and even less Monsters who have a Time-related weakness or resistance. In fact, only Chaos has either (and it is, unsurprisingly, a resistance). You won't run into any Time attacks until you face the Death Eye and Lich in the Temple of Chaos Past. Ribbons resist Time, as does the Black Robe, but NulAll is the only other way to gain resistance.
