I think they give some kind of meaning to the entire universe.
The universe mostly consists of particles that just exist. For inanimate things that do not perceive the flow of time, a Planck time is the same as the universe’s entire lifetime. So without sentient observers, time would make no sense. The universe would instantly jump from its initial state to the final one, so it might as well not exist.
It’s like in that philosophical question about a tree falling in the forest where no one hears the sound, but instead of the sound it’s about time and therefore all existence.
Sorry for bad English, I hope I made myself clear.
