You can even rest during this time, re-prepare time stop again, ready an action in the last round of it, and re-cast it again. You can set up spells to kill a monster as soon as the time stop ends, and gain as much XP as you want through this.

Given time, this can probably even kill pun-pun! You just get yourself to epic level, create an epic spell that does area of affect force damage, and use this on him over and over. You can SLOWLY take him down, and theoretically, by readying an action, never let him do anything.
Doesn't work, RAW.

See, Clerics prepare spells at a particular time of day. Even pulling off a 24 hour time stop... time isn't passing. That time of day doesn't come around in your 24 hour break. You can't prepare another Time Stop, and so you run out.

Now, if you've got a Wizard/Incantatrix build, on the other hand....
