Hello, When I do std::cout << boost::posix_time::time_from_string ("2008-06-26 0"); output is 2008-Jun-26 00:00:00 But when I do std::cout << boost::posix_time::time_from_string ("2008-06-26"); output is 2008-Sep-17 16:06:26 Isn't a bug ? Even if this format is not accepted, should not it throw an exception ? J. Bedouet
