Oh yes it does. (I feel I am getting into practise for panto season).
you do not get 24:00:01.
That is true. ISO 8601 specifically states that if the hour value is 24 the minute (and seconds) values must be zero.
A day is 23 hours 59 minutes long.
If all the modern tech with internal clocks worked on 24 hours then everything would happen an hour later every day
No. 24:00:00 on Monday is the same as 00:00:00 Tuesday.
The time tells you how many complete hours, minutes and seconds have elapsed since midnight. That can be 24:00:00 after the midnight between Sunday and Monday, or 00:00:00 after the midnight between Monday and Tuesday. The context will determine which makes the most sense.
