John: You're making the common mistake of characterizing 24-hour time as military time. The military uses 24-hour time because, quite understandably, they don't want any ambiguity. They certainly didn't invent it. These days, almost all countries use 24-hour time for schedules (radio, TV, conferences, meetings, etc.).
24-hour time has been with us ever since the day was divided into 24 hours. A more relevant question is why and when it was subdivided into two 12-hour periods. I don't know the answer to that. Students of horology probably do know it, though.

I tried to find it on Google but couldn't seem to. Thanks
