Use Calendar.HOUR_OF_DAY instead of Calendar.HOUR in QuietTimeChecker

        Integer endHour = Integer.parseInt(quietTimeEnd.split(":")[0]);

        Integer endMinute = Integer.parseInt(quietTimeEnd.split(":")[1]);

        Integer now = (gregorianCalendar.get(Calendar.HOUR) * 60) + gregorianCalendar.get(Calendar.MINUTE);

        Integer now = (gregorianCalendar.get(Calendar.HOUR_OF_DAY) * 60) + gregorianCalendar.get(Calendar.MINUTE);

        Integer quietStarts = startHour * 60 + startMinute;

        Integer quietEnds =  endHour * 60 + endMinute;
