inside a watchface, is there a way to get the time format when it is set on 'military' ?
I can access to 12 or 24 hours but can't find any API for military setting.
When the watch is set in military (not all watches have this), it will show as 24hr mode, and there's no way in a watchface or app to see if it's also military time. What you can do is add an app setting for your app, with a boolean like "if in 24h mode, use military time", or just always treat 24hr mode as military.
