This was a fun read, in a large part that I too share an intense curiosity around the question "What is time exactly?" That was brought on in my third semester of physics in college where we dove into quantum mechanics and the whole question of why you can't travel faster than the speed of light revolved around the fact that at the speed of light, time stopped. (insert mind blown gif) That was me, struggling with that idea. When I went to work at Intel I learned all about 'electron tunneling' as something that caused EPROMs to fail and gates to change state, and why semiconductors with smaller than 1 micron features probably wouldn't work (smirk). But I had not seen the Hartman paper[1]. What I found most interesting about the Quanta article is the discussion about how to measure time at these scales. And just recently there was this article on zeptoseconds[2]. I can't help but think something amazing is going to come out of all this work. It may be a parlor trick but it is going to be a really cool parlor trick.
