I'm watching the interview with Leslie Lamport[1]. The recurring subject is the arbiter problem. Essentially: "which came first" is not solvable in finite time in general as time differences approach zero. Then there's some mention about discrete vs. continuous, and time differences and frequencies (non-discrete entities) used for information representation in the brain. Now this makes an old itch surface. I'm far from being able to express it, but it has to do with sigma-delta modulators (binary representation of continuous signals) and cross-modulation of near-equal square waves where arbitrary short pulses can arise.
