Hi David, > Where would you use it?

The other party cannot ask us which 10 -o'clock we mean. When I write 22:00 each knows it is 10 in the evening. On the other hand, when we do talk to someone face-to-face we pretty much always use a 12-hour clock because most of the time we use the time as part of a conversation where an event is being discussed and we need to tell when that event is. Having dinner at 6 is pretty much always at 18 and almost never at 06. ;-)

Yup, I have seen it go wrong with a band that thought it would be neat to have a concert starting at midnight and got it wrong on their tickets. :-( Someone did not realize 0:00 is just one minute before 0:01 on any given day and 24:00 is just one minute after 23:59 on any given day.
