I really would like an option to change the 24-hour clock to a 12-hour clock. I don't really know how 24-hour clocks work; it's kind of a pain having to constantly Google it or count it out to get the correct time on this game.
One of the cool things about video games is they can teach you new things if you want to learn about them. A cool trick I use for the 24-hour clock is just don't stop counting at 12. The times in the morning are the same, but once you hit noon 1pm becomes 13, 2pm is 14 and so on. I'd imagine having to Google that is a pain, sure, and maybe you won't need to use a 24-hour clock in your life right now, but thanks to WOS you just learned a new way to tell time!
