Duh, but for both Clark and Superman, it's one month even if it looks longer than a month. Like I said, both DC and Marvel began the one month theory for story arcs during the early 90's. The events of the Knight Trilogy over in the Batman books was said to have been a month or two. Yet we clearly see large passages of time.

>Superman's long hair would be a factor in "Dead Again". How this works post "Infinite Crisis" hasn't been said yet. Though I'd wager that it'd be J'onn.

Uh, Clark had been tested to determine if he was in fine physical shape. So unless Clark made the robots to be 100% organic enough to fool a doctor, I'd doubt it. J'onn, like Matrix, could.
