Description

In my application, I read date from database, and write it to other table.
Date "0000-00-00 00:00:00" is bad converted to php, and cannot be saved back to mysql.

Exception:
SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect datetime value: '-0001-11-30 00:00:00' for column 'date' at row 1

Steps To Reproduce

In database I have date "0000-00-00 00:00:00", data type is datetime not null. InnoDB.
I use simple NDBT select

$row = $this->table(..)->wherePrimary(...)->fetch();
echo $row->date; // prints "-0001-11-30 00:00:00"
// and write it back
$this->table(...)->wherePrimary(...)->update(['date' => $row->date]); // it throws exception, mysql cannot save this date

PHP 7.1.2, mysql 5.6.22, I use InnoDB for all tables.
