Typed property User::$DateCreated must be an instance of DateTime, string used

My main question is if there is support for object properties in PDO?

I'm looking to go straight from my sql results to the User class. I know I can create an interpreter-type class but I was hoping for a straightforward solution. Can anyone help, please?

The error is as follows:

Typed property User::$DateCreated must be an instance of DateTime, string used

This is my php class

class User
{
    public int $UserId;
    public string $Username;
    public string $Email;
    public string $PassHash;
    public DateTime $DateCreated; // problem area
    public bool $Active;
}

And this is how it looks in the db

mysql> desc Users;
+-------------+--------------+------+-----+-------------------+----------------+
| Field       | Type         | Null | Key | Default           | Extra          |
+-------------+--------------+------+-----+-------------------+----------------+
| UserId      | int(11)      | NO   | PRI | NULL              | auto_increment |
| Username    | varchar(30)  | YES  |     | NULL              |                |
| Email       | varchar(200) | YES  |     | NULL              |                |
| PassHash    | varchar(250) | YES  |     | NULL              |                |
| DateCreated | datetime     | YES  |     | CURRENT_TIMESTAMP |                |
| Active      | tinyint(1)   | YES  |     | 0                 |                |
+-------------+--------------+------+-----+-------------------+----------------+

I'm calling it with this function, which is breaking because it's trying to push a string in into a DateTime property

public function GetUsers() : array
{
    $sql = "SELECT UserId, Username, Email, DateCreated, Active FROM Users";
    $stmt = $this->db->prepare($sql);
    $stmt->execute();
    return $stmt->fetchAll(PDO::FETCH_CLASS, "User"); 
}

However, when I run this code, it returns a DateTime object, just like you'd expect.

public function GetUsersThisWorksTho() : array
{
    $sql = "SELECT DateCreated FROM Users";
    $stmt = $this->db->prepare($sql);
    $stmt->execute();
    return $stmt->fetchAll(PDO::FETCH_CLASS, "DateTime");
    // this works. It actually casts the result as a php DateTime object
}
