No i don't think he does get the credit for time served. He wasn't in jail like the other guys. I think the time meter started up on Staino the day he surrendered after he pled guilty.

I'm not 100% on that, but i'm pretty sure thats how it works.

Was he under house arrest? Did he have an ankle bracelet restricting him to his house? If so he might be able to call that time served. But i'm not sure on it.
