Enwin's 24-hour clock 1.1.0

This should always be a choice.

Nice one

Good catch. They have a user option for it, ClockFormat, but don't actually use it. I don't know much about mods nor js but I believe:

Configuration.getUser().getValue("ClockFormat")

will get you the value from the UserOptions file.

Thank you for the fast fix! Now it's perfect
