Are people thinking that a 24 hour time is metric? I saw a couple of comments that make me think this. In Australia we use 12 hour am/pm almost all the time, even on official documents. We've been metric since the early 70's. I still have to pause and convert when I see a time greater than 12 (or, sadly, less than 1.) It seems much more a cultural thing, that one. Now if we could only stop anybody using m/d/y date formats...
