Alright. What I had in mind were illusions that affect the mental perceptions of other beings in such a way as to make it appear as if time was slowed, sped up, etc. As for Divination, it would be the standard process of casting a spell to find information or to see a few seconds/minutes/hours into the future. That type of thing.

Of course I could go with a completely different mage type, if you want.
