I think you mean 0000 UTC.
As you may remember, though, I've made that mistake, myself, too. (Senior
moment? Brain fart?)

Although I don't like 2400 myself (since there is no 2401 or, for that matter, 2400:01; and since there has to be a boundary when one day ends and another begins and the most logical one is 2359:59 to 0000:00, I think ISO 8601 allows it, to mean "midnight approached from the previous day" or something like that.
