Then the day starts (like always) 1 second after midnight with 00:01 then continue with one o'clock being 01:00 continuing until 24:00 which is midnight and only last for one second. So if every hour has a number between 0 and 24. Your example would be 15:15. I saw an episode of Friends last night where Monica says, just subtract 12, an easy way to do it e.g.
15-12=3 or 18-12=6.
Sorry if my explanation is messy and sorry if I misunderstood your question completely.
