This is an interesting point.
Given a universe with but one unstable particle, it will decay at some point, and it would be indistinguishable if it took a year or a microsecond to do that. Time would be meaningless. But given two different particles, suddenly one has a measurably greater probability of decaying than the other. Time is still sort of meaningless, but that very real probability of decay makes it not totally meaningless. That's just two particles, and already we can see 'classic' time emerging.
