Why ?

Even if the simulated time does not correspond to the real time the

probability of the prisoner finding himself in the simulated world is 1/2.

Unless you solve Jacques Mallah's desperate implementation problem

(see the archive or Mallah's URL) you will not be able to use "time"

to define the measure on the prisoner's experiences.

prisonner, if COMP is correct, he cannot make any difference

space) is a construction of the observer's mind and is defined only in a

relative way. What you need to do is to defined a notion of first person

(or subjective) time *from* the measure on the possible computationnal

continuation of the prisoner's mind.

Note also that there is no "real" time in any many-world view of

relativistic quantum mechanics (even without COMP).

With COMP (which you are using here) there is no real time nor is there

any need for such a thing.
