shifting the topic slightly, I've noticed that FM Osaka lists their 
programme times sometimes as times even later than 2400 (which I 
intuitively but perhaps incorrectly interpret as meaning tomorrow)

For example,


appears to show 'music coaster' as playing at 25:00 -> 27:00 in the 
japanese text, and 1am - 3am in the english text. (25 = 1+24, 27 = 3+24)

The days don't seem to match either -- or rather they do: japanese text 
seems to say (as much as I can read) mondays->weds at 25:00->27:00, whilst 
the english says mondays->weds at 1am - 3am.

Has anyone seen that before?
