timeMod variable

[boomboo]

I've noticed that the cooldown frames behave somewhat odd when various time passage mechanics are involved, I belive Madness: Desynchronized uses it as well as global CDR effects to some extent.

I think the minDuration doesn't work well with but not only, I've noticed some odd interactions where the spell goes on cooldown but the frame doesn't update properly until a second or so later.

I'm not sure if that is in some way related to timeMod returned by _Aura or if it needs to be at all referenced by cooldowns.
