I suspect it’s pretty important (for the lay reader) to be clear in distinguishing between the question “what is time” and the question “how do we perceive time.” Your article appears to begin with the first but then morphs into the second without clear delineation, which may be confusing to people.

One of the big questions in quantum physics is the question of granularity. We know there’s a Planck constant (the minimum value for electromagnetic action which is indivisible) but is there a space constant and is there a time constant? In other words, at the quantum level, does time move smoothly or in tiny discrete “hops?” No one knows, as our machines aren’t sensitive enough to measure time at this level and the theoretical equations are ambivalent.

Human perception of time, by comparison, is a relatively trivial phenomenon determined by largely neurochemistry.

Both questions are interesting when explored in depth, but each needs its own article.
