Your preferred time format?

12:00 because of common sense. If someone say hey, I will meet you her at 4 o'clock and it is already 9 am, I am pretty sure they known your talking about pm.

24-hour. But I use mostly the 12-hour one when speaking.

We do the same in France, as 24 is the standard here.

Sometime when speaking we do use 24h too, like when I'm at work and people ask the public opening hour, we do tell them in 24h system.
But when someone ask for the actual time, we use the 12h system.


And like someone said earlier : When writing, people are confusing AM and PM.
in France afternoon is told "Après Midi" (literally: after 12 o'clock) like AM ¬_¬, so people who didn't learn English doesn't understand why afternoon would be PM when there's already corresponding letters.
French people don't study English and are very bad in learning new languages, there's something like "preserving the patrimony and don't use anything else than French" custom and a bad quota ratio law for foreign languages on TV and Radio. I'm jealous of north European countries, they learn and speak English very well.
