i do seem to find that judging 'how much time i have before 'x' o'clock'

That is a matter of simple math. It seems to work better for people
lacking those skills if the appointment is on the hour.

i will confess math is not my strong point, but i think it might be more
that i grew up in an analog clock world, not digital, and sorta learned to
'judge' time then. but it doesn't make much sense, i admit.

Makes a lot of sense to me. There's not just one "right" way of doing
things. My wife has been pretty involved in elementary school math
curriculum for the past fifteen years, both in choosing, approving and
volunteering in the classroom, both to help and to see how it is
working. Fifteen years ago they adopted a curriculum using
"manipulatives". That means little doodads that the kids can actually
touch. For instance, when learning fractions, there will be plastic
circles and parts of circles. When you put four quarter circles on top
of a circle, it gets real clear what a "quarter" or "1/4" is. When you
put two quarters on top of a half, it's equally clear why two quarters
are the same as one half.
