Past your 4th word, I can't understand what you're trying to say.

Ok, it confuses me that you think time is mesurable with 10.

Someone decided to use Base 12 & divide the day into 24 hours, divide hours into 60 minutes & divide minutes into 60 seconds. It wasn't discovered, it was invented.
The same can be done with a Base 10 system. Divide the day into 10 or 20 hours, divide hours into 100 minutes & divide minutes into 100 or 1000 seconds.

Do you understand this part :
Someone decided to divide the day into 24 hours, divide hours into 60 minutes & divide minutes into 60 seconds.

Sure, someone must have invented the concepts. Applied some measurement to the facilities to measure time and therefore had some general me aning beind creating a measurement of time .... Which would only mean that that they didn't understand how to measure time other than with some meathod.

Waitress : Would you like your pizza cut into 6 pieces or 8 pieces?
Stranger : Better make it 6 pieces. I don't think we can eat 8.

The same way a pizza can be cut into 2 pieces, 4 pieces, 6 or 8, the day can be divided into 24 hours or 10 hours or 20 or 60. The hour can be divided into 60 minutes or 100 minutes or 7000 minutes. The minutes can be divided into whatever number of seconds we want.
Of course, each hour in a 20 hour day (on Earth) will be longer than each hour in a 24 hour day. By dividing it differently, we have different sized pieces.

If you look at a clock that says "11:59", what does that tell you? That the current time is exactly at the point you mentioned, the first point in time of the 60th minute?

So, consider the one second that passes while the clock displays 11:59:00...
You think that second is part of the 59th minute?
Or is it the first second of the 60th minute?

Then why do you care about 12 hour time?
You obviously have an opinion about how the 12 hour time should be implemented (that's the whole point of this thread), so why don't you want to answer the question?

Isn't it a little more interesting to just say,

Why not just:

000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000~1

I guess you might say what leads infinite zeros. Or whatever.

It's of no use to 99.99% of people. It's not practical.

What happens if you reverse the 0s then.
Say there IS 10 time measurement.
This would mean..that the 1 would face 0 for eternity and that isn't practicle is it?

The one would be infinite?

We could also say consider the hundredth of a second that passes while the clock displays 11:59:00:01 & consider the nanosecond that passes while the clock displays 11:59:00:00:01, etc, etc, etc.
You're diving into a bottomless pit of useless minutia.

The title & OP indicate otherwise. The topic was where in time midnight is & how should it be defined.
The OP even mentions both 12 hour mode & 24 hour mode.

It tells me that 11 hours 59 minutes have passed.
If you look at a clock that says 11:59:17, what does that tell you?

Do you think it is possible for someone to become unaware at the time when shift change occurs.
