It's the buff that actually reduces your Cooldown on skills by 20% (300 Sec Cooldown *0.8 = 240 Sec Cooldown), but the benefit is not retroactive, meaning if your skill is already on cooldown and you receive the buff, that particular skill will not benefit from it.
There are actually two different cards, one which does as you describe, but then there is another with a 10%(25%) speed buff. (Can read more here and here.) I do have to wonder if the buffs from Selene will have their percentages adjusted in light of how skill and spell speed will work in 3.0, but in the meantime I'll assume they will be left unchanged.
