Which one is correct?

Not a teacher.

Neither.

It's "twelve noon," "twelve-o'clock noon" or just "it's noon"

Simply It is 12 pm (post meridiem).
I wonder why using "pm" not "am" ? The time at 12 noon is the meridiem. "pm" or "am" doesn't express this time exactly.
Or we can't use "pm" to say "It is 12pm", can we?
Thank you !

By convention noon is 12 PM. Any digital clock will display it that way.

At the very moment of noon, it is neither AM or PM, but as soon as one second has expired it is after noon, or PM.

I don't agree. The 12-hour clock divides the day into two 12-hour periods, not into two periods of 12 hours less a second and two one-second periods.
p.m. starts at exactly 12 noon and ends at exactly 12 midnight, when a.m. starts. The fact that "p." stands for 'post' doesn't mean that p.m. can only start at some time after noon. If it were so, what's magic about one second, why not one minute or one microsecond?

I agree, that's why I said it was a convention to call noon 12 PM.

But logically we can not say that 12:00:00.000 is "post meridiem." Noon can not be after noon.

Logically, that is.

I would say "12 noon" or "12 midday".

Regardless of the semantics involved, we do also say "12pm" (midday) to differentiate it from "12am" (midnight).
