Yes, you are right, of course.

Thank you and the others on this thread for the input.
I am summarizing the result (at least what I extract of it):

- 12am is beginning of the day, same as 0:00
- 12pm is noon.
- Times like 24:13, 25:14, and even 13:12pm will be tolerated,
  mainly because the regular expression I have for finding times.
  matches them (it is something like [012]?[0-9].....
  The agenda will list such times after midnight.  You need to
  decide for yourself if this is more useful than confusing.
  The way these nonstandard times will show up in the agenda is:

    23:58
    23:59
    24:00
    +0:01
    +0:02
     ...

  The hard limit for this game is 29:59
