I wouldn't automatically assume that it's even a psychic ability at all. I'm not knocking the idea that it is, but giving thought that it might not.
Also, a premonition is when you have an instinctual feeling you can't quite place about something happening in the future. Precognition is when you actually know what is going to happen, whether it is simply knowing, hearing, smelling, seeing, tasting, or feeling.
Divination itself means to know of something purely by psychic means, this includes the future, present, and past. Since divination is used largely on the Astral level, it can also pertain to Astral laws of existence rather than physical. In the Astral, time is everything at once, not just past, present, and future.
