DateTime 12-hour formats (AM/PM)

The documentation for "NumPad.DateTime" specifies to use "dateFormat" values supported by "moment.js", which is great, but when try to use a 12-hour time format with AM/PM (e.g. "h:mm A"), there seems to be no way to specify the "AM/PM" portion of the time. 24-hour time formats work fine (e.g. "HH:mm"), but in the US those are primarily used only by the military.
