So here's the feat. It doesn't seem to mention the normal time. It doesn't seem to explicitly let you cast a spell, although what it does functions as raise dead. It doesn't seem to explicitly let you cast raise dead as an SLA either. Nor does it seem to be normal LoH that has a different effect.
So how long does it take? Normally, feats that let you do something new specify the time it takes to do so. This does not. What do I refer to instead?

1 minute seems the safe option. It is both the casting time of raise dead and number of rounds worth of standard action LoHs you are required to use.
I can see an argument for treating it as a standard action, either as an SLA or simply the default unspecified action, but it isn't as attractive from a balance perspective imo.
I would not argue with either option decided upon by my GM.

Well...it says "as a raise dead spell," so I think that would mean that by any parameter not otherwise covered, it follows the same rules as the raise dead spell.
The "... to bring a single dead creature you touch back to life" part before the "as" heavily suggests that it's not the action that is "as", it is the effect.
That said, 1 minute is a very reasonable guess in my eyes, but I was hoping for a bit more than guesswork here.
