I still don't have a simple coherent understandimg of how time works after 10 years of research in fundamental physics. Im quantum field theory, time is a continuous parameter like the three+ space directions, but distinguished from space via the metric tensor. Yet, time is not entirely separate from space because in relativity, which direction in the four dimensions one calls time is not uniquely defined.
The *direction* of time, i.e. the reason why past and future are so different, im classical physics seems to be a purely statistical phenomenon. A space like boundary of the 4D universe with low entropy is the past. But once I thought I got that a little bit, I got confused again because in quantum theory (at least in the usual picture) we have wave function collapse which fundamentally seems to distinguish past from future as well.
