getDateInMillis API should also set millisecond to 0

[MilkBiscuit]

MonthAdapter.java Ln118

        public long getDateInMillis() {
            if (calendar == null) {
                calendar = Calendar.getInstance();
                calendar.set(year, month, day, 0, 0, 0);
            }
            return calendar.getTimeInMillis();
        }

Should also call
calendar.set(Calendar.MILLISECOND, 0);

And same issue exists in setDay(int year, int month, int day) of MonthAdapter.java
