Where was the time limit mentioned?

That's a good question, I somehow doubt Kishimoto thought about that. I didn't mean that summonned animals live in completely another dimensions, if that's what you thought. Yeah, they surely live in the same dimension, though with the summoning technique, they are basically bound to their home and will inevitably return to it, when the time limit expires. Yeah, there was such a limit stated, Gamakichi mentioned it after his attack on TTJ Obito (that he wanted to do something useful before the summoning ends). And I think that during Nine-Tails attack on Konoha Minato also said that Tobi (Obito) couldn't keep Kurama's summon indefinetely, though it was already an impressing feat.
