Only if you want it to be.
Honest question though.
From a data perspective it is a null interval, an interval of 0. I may be looking at it from the very lopsided view of my experience though… Most folks are smarter than me so I’m willing to think about being wrong.
Hugh has it right. We can talk either way. My point is the same good one no matter what language or terminology we decide to use to express it. I was using ‘interval of time’ to cover intervals of non-zero duration. (But you already understand that.)
If we want to use ‘interval’ in the way that also counts times of zero duration, then what we would need to observe is that “midnight is not an interval of non-zero duration.”
The underlying point is the same and can be expressed with any terminology adequate to the subject.
But as far as I can see there is no cash value in this discussion to using ’ interval’ in that slightly wider sense. It would just make making the same point a little wordier.

A tad background on my rational and why I was asking…
A large portion of my job is managing a systems data tool. We consider “point in time” (PIT) an entity of 0 duration/interval but with attributes. Think of a photo (we actually call them PIT snapshots). We also have “aggregate view” which is more like an average. Think a long exposure but replay-able like a video since it is made up of many PIT. It isn’t the easiest thing to explain.
In my maths days I would have said that a point is a null entity with only 4D location attributes (time, X, Y, Z) and since time is an attribute of a point, time can not be a point itself. As my brain has softened (as well as my middle) I’m more confused by the absolutism of that idea than ever. Time was a point when I kissed my wife this morning. Yet time was the attribute of the kiss. And the wife was an attibu…
Kiss…
Wife…
Mmmm…
What were we talking about?
But let us not muddy the temporal waters with metaphysical worries about the nature of time.
And what are we here for anyway? To settle Foxtrot’s hash, that’s what.

p.s. I am so unhappy with the title given to this shunted thread. First, because the issue is not only solvable but resolved! (Pat, pat.) But more importantly, it ought to be called ‘In Which Foxtrot & Company Try Pigfender’s Patience’. Another in a fast-growing series!
Sorry about butting in late, but… 12:00 am can’t be midnight. 12:00 pm is, which coincides with 00:00 am. 12:00 am is midday, noon.
Unless one of them is a Nomstrailian who is 180° off on everything. Nomstrailians have it rough spending their entire lives using toe strength to keep from falling off the planet…
Apparently conventions actually differ as to how to represent midnight on the clock.

Sorry lunk, at least in English speaking countries (with the singular exception of the U.S. Government Printing Office in 1953) 12am is midnight and 12pm is noon. Maybe it’s different in Sweden?
The conversation was fun, but the regulations, conventions and history of use are clear and consistent (see my comments above about New Year, 12:01am, etc).
I’ve got work to do… 
Well, it’s already Thursday here, and I stayed up last night to check what happened at midnight. It was 12am. Today. Since you are behind the times 
you can still do the same…

No, “midnight” is a label assigned to the 00:00 hour starting the new day, just like “noon” is a label assigned to the 12:00 hour in mid-day.
Well, considering other “logical” systems the British have invented, it makes sense that you count the hours starting at 12 and ending on 11. How do you teach kids that logic?
“No, you don’t start at 0 or 1, you start at 12! It’s 12, 1, 2, 3 …”
“So I have nine fingers?”
No… You have eight, obviously.
To the majority of THE RED LION’s erstwhile philosophers and amateur astrophysicists, Midnight was when one day ended and the next began. I suppose we should’ve known better.

You forgot “willing to do things that normal people think are insane.”
Like posting in this thread?
You’ve highlighted the flaw in your own reasoning: You’re assuming it’s logical. As you said, consider the other systems that the British have invented*.
I’m not defending the system — I don’t claim it’s brilliant or sensical — I’m just stating what it is.
[size=85]*To be fair to the Brits, they’ve made a decent go at democracy, but this is tempered but their insistence on a democratic monarchy. [/size]
I can’t speak for Canadia or Nomstralia, but in the UK is we actually don’t have a monarchy, constitutionally speaking.
They barrow your non-monarchy as their own.
Don’t mess with me at this late hour of the evening. You have a queen as head of state. Ergo, you have a monarchy.
I’m getting too old for this… <end of sentence obscured by David Sanborn’s “Murtaugh” saxophone riff from Lethal Weapon>
