Now this feels very awkward to me, because I'm not sure whether you're joking. So I'm sorry if I've taken it the wrong way in replying!
Apparently, it could be referred to either way:
"In the 24-hour time notation, the day begins at midnight, 00:00 or 0:00, and the last minute of the day begins at 23:59. Where convenient, the notation 24:00 may also be used to refer to midnight at the end of a given date - that is, 24:00 of one day is the same time as 00:00 of the following day."
All the more reason, I think, to specify a time that's one minute to either side for optimum clarity!
