Garmin Developer set 12-hr time

gistfile1.txt

On my watch the 12/24 hour setting is in

Settings->System->Time->Time-Format

You can use it for example like this:

var time = Gregorian.info(Time.now(), Time.FORMAT_SHORT);
var deviceSettings = System.getDeviceSettings();
var is24Hour = deviceSettings.is24Hour;
var hour = is24Hour ? time.hour : 1 + (time.hour + 11) % 12;
var pmString = time.hour >= 13 ? "PM" : "AM";
