Don’t know, tbh, I’ve seen it in Japan and kind of figured it might exist elsewhere too. Since OP provided no further context, I thought I’d mention it.
Ever since I saw it in Japan I realized that it’s just the best way. It eliminates all confusion about what “1am Tuesday” means. And 27:59 rolling into 4:00, or 28:59 rolling into 5:00, makes perfect sense since 4-5am is a normal sunrise time most of the year in Japan
I have never in my life seen anyone write the next day as e.g. 25:00.
It would be rather something like 1:00+1 or whatever.

Now you have.
Interesting, just a Japan thing then or is this used in other places?
