24:37 is exactly what I'd call a hack.

It creatively abuses the lack of range checking in the format, and stretches the human facility of "knowing what I mean". It does not match a real time, though, because no clock shows this time as a current time.

While neat, it's a hack, a way to bend the notion of time, and as such, it ought to cause problems. Fortunately, airlines never seem to use this hack, and are able to indicate "00:37 next day".
