Time in Buddhism

I read a couple of books on time, yet they all seemed somewhat incomplete, as if it was something simply tagged onto the rebirth / enlightenment doctrine. How important is *time* in Buddhism, not simple "impermanence" but how impermanence is housed. Or is there nothing to time beyond **impermanence**? I saw on philosophy stackexchange, something about this, but I'm getting quite a bad reputation there... Do "people" experience time? Is an experience of time actual time? Because I think that if so, that's where the biases and make believe of comtemporary science, collapses !! Thank you so much :)
