Res timer?

[Zenshu]

What are the times for Ressing corpses? I searched the forums and found one archived post where the entire thread got derailed by people moaning and cruying about Corpse decay timers and no one ever answered the OP's question about the res times. I ask because my AKS was unable to be ressed after less than 15 minutes so I am very curious to know what the timers are set as for being able to res.
