> US (and maybe one or two English-speaking countries) are the only ones using 12h time, the rest of the world uses 24hrs, however 12h _sometimes_ is used India uses 12h time (except in military talk; & railway timetable display boards) in day to day life. I have never heard in 29 years somebody using 15 as 3, or 20 as 8pm. Even till few years ago, atound 2008, flights times at Delhi Airport too were displayed in 12h, on mechanical card spinner display board (where a card with letter falls & next one comes, on a roll until desired letter comes). Seeing that board as a kid was highlight of my childhood trips to airport.rt.
