I am self-aggrandizing when I mention someone else's book? Wow! Great logic.
Check the literature; Chronons are out of fashion and have been for some time. For example, TSQL projects have had about 18-20 people working on them, all with a decade or two in temporal data and they reject that model. Jan Hidders is more to date of this than I am, if you want current info.
I do not need to materialize Aleph null or Aleph one rows in a table if I can test any requested value to see if it is an element of the set. Remember basic set theory? I can either enumerate a (finite) set or I can give a membership rule (infinite sets). Then we argue about what rules the rules must follow. Dedekind cuts at pi and all that jazz.
