DateParser::parseFormatted(string, format) - Parsing dd/mm/yyyy ?

I'm trying to parse the below date using the DateParser::parseFormatted method but I'm not having any luck.

I can use this method but for a date string formatted dd/mm/yyyy it outputs the wrong year.

How do I correct this.

d.year should equal 2016 but instead I get 2020 because the only date the date parser seems to take is dd/mm/yy

#include <iostream>

#include <ql/quantlib.hpp>

#include <ql/utilities/dataparsers.hpp>

using namespace std;

using namespace QuantLib;

int main()

{

Calendar cal = Australia();

// convert a string to a date.

string mydate = "05/08/2016";

const Date d = DateParser::parseFormatted(mydate,"%d/%m/%y");

cout << "The year of this date is: " << d.year() << endl;

}

Use %Y (capital Y) for 4-digits year. The parser uses Boost.Date internally; the complete reference for the format is at <http://www.boost.org/doc/libs/1_61_0/doc/html/date_time/date_time_io.html#date_time.format_flags>.
