David, you are scary. "two clock tics" or two successive "nows"?

Because the light source is moving away from the observer making a
longer distance for the wave (not changing wave length) to move
(number of quanta) to reach the observer.

Light changes position at one quantum each now, the number of quantum
changes over number of nows can vary. Humans can think of time as a
concept because we have memories. We know of past through the
existence of matter deposits (memories retained in soil or other
artifacts). Each quantum of now is a result of all prior space
changes of energy plus vectors resulting from past changes. Nobody
can experience the past except through memory stuff. Nobody can
experience the future, to do so would require the future to exist now.
