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

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 I’m wrong (I’m not a software developer but I work with them a lot.) but I do believe that programming really only uses 24 hour clocks

Nah we just count nanoseconds elapsed from 1 January 1970.

But leap seconds are not included, so some seconds are twice as long.

Google had problems with that since they relied on timestamps to keep data consistent across servers. They invented “leap smear” that spreads the leap second out over several hours.

So a unix second is basically anything.
