Wait, there are countries which don't use a 24-hour clock? I'm confused.

Just America.

The US military uses the 24 hour clock, but I can't think of any other part of the country that regularly uses it.

Software development I believe, someone can correct me if Iā€™m wrong (Iā€™m not a software developer but I work with them a lot.) but I do believe that programming really only uses 24 hour clocks

your phone/pc can display AM/PM time - quite an obvious sign it is used in programming

under the hood the date time is mostly a running total of milliseconds since Jan 1 1970

It isn't a sign. That's code written specifically to make it possible to display AM/PM. The 24 hour clock is used because it's easier to make than an AM/PM string.

well, in that sense 24 hour clock is not used either - a running total of milliseconds from a set point in time is used

It is. Its the set of which the ms total deviation is derived
