You seem to assume that a day always has 24 hours. Common (but not only) non-24h day lengths are:
- 23 hours
- 25 hours
- 24 hours 1 second
- 23 hours 59 minutes 59 seconds
You could assume that a day isn't exactly 24 hours, but it's close-ish to 24 hours. Nope, not even close.
And that assumes that we can treat an hour as a precise measure of time (we can't). On some systems, even a second is not a precise measure of time (second smearing).
To make things worse, those are "simple" edge cases.
Time is hard. I'm not sure if I can make any statement about time that is true.
