When you summon this undead where does it appear? IS it like the summon monster spell, and attack the turn it comes?
Raise the Dead (Su): As a standard action, you can summon a single skeleton or zombie to serve you. The undead creature has a number of Hit Dice equal to your oracle level. It remains for a number of rounds equal to your Charisma modifier. At 7th level, you can summon a bloody skeleton or fast zombie. At 15th level, you can summon an advanced skeleton or zombie. You can use this ability once per day plus one additional time per day at 10th level.

Since it's only around for a few rounds, I think it should get the full benefit of those rounds. It does say summon, not raise, so you're conjuring it into existence, rather than causing a fully-dead skeleton you're lugging around to animate.
