You are mixing "points in time" and "duratation". <g>

Are you counting or measuring, then? And what _is_ the difference in this case?
You could say that you "measure" the time (of day) when reading your clock, but that's an unusual use of the term "measure".
You can't count the time (of day). You can count (ie. measure) the duration
in hours, eg. of a day.
Any meaningful measure (in the mathematical sense) of the duration of a day
yields 24 hours. Instead of counting you might subtract begin-time from
end-time.
Here comes the represenation 24:00 in as handy: Duration = 24:00 - 00:00 =
24 h!
