“What we’ve done is to show that even if time is a perfect, classical and smooth parameter governing time evolution of quantum systems,” Huber said, “we would only be able to track its passage” imperfectly, through stochastic, irreversible processes. This invites a question, he said: “Could it be that time is an illusion and smooth time is an emergent consequence of us trying to put events into a smooth order? It is certainly an intriguing possibility that is not easily dismissed.” https://www.quantamagazine.org/the-new-science-of-clocks-prompts-questions-about-the-nature-of-time-20210831/
