A physical theory of time?

From Dan Falk at Quanta,

Many physicists have made peace with the idea of a block universe, arguing that the task of the physicist is to describe how the universe appears from the point of view of individual observers. To understand the distinction between past, present and future, you have to “plunge into this block universe and ask: ‘How is an observer perceiving time?’” said Andreas Albrecht, a physicist at the University of California, Davis, and one of the founders of the theory ofcosmic inflation.

Others vehemently disagree, arguing that the task of physics is to explain not just how time appears to pass, but why. For them, the universe is not static. The passage of time is physical. “I’m sick and tired of this block universe,” said Avshalom Elitzur, a physicist and philosopher formerly of Bar-Ilan University. “I don’t think that next Thursday has the same footing as this Thursday. The future does not exist. It does not! Ontologically, it’s not there.”

Ontologically it’s not there only if one has some reason to think that the future will not arrive.

Last month, about 60 physicists, along with a handful of philosophers and researchers from other branches of science, gathered at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, to debate this question at the Time in Cosmology conference. More.

Well, there is apparently a faction in favor of a physical theory of consciousness (perceptronium). So why not time?

Time is real and PHYSICAL. You can prove that yourself from Einstein's own equations. See: "Beyond Einstein: non-local physics" by Brian Fraser (2015) Note how "physical time" enters into the equations of physics, such as gravitation.
