Hmm. 12:00PM implies twelve hours past midday (p.m. = "post meridian" = past
midday). That would be midnight. From there to 7:46PM means the ac has been
on for almost twenty hours.

Of course one could also say 12:00AM (a.m. = "ante meridian" = before
midday) which would also be midnight.

So they both mean the same thing! Wow, I thought I had this worked
out when I was 45 y.o. Now I have to start all over. Maybe NASA
could come up with a numeric term for noon, or I'll have to start
usilng a 24-hour clock.
