time with milliseconds is not handled properly

[mikeTWC1984]

Steps to reproduce:

        var duckDbCommand = connection.CreateCommand();
        duckDbCommand.CommandText = "select  now() as tme";
        var reader = duckDbCommand.ExecuteReader();
        reader.GetDateTime(0)

This will crash with below error

"Valid values are between 0 and 999, inclusive. (Parameter 'millisecond')"

now function returns time with milliseconds. If specifying time without milliseconds (e.g. TIMESTAMP '1992-09-20 20:38:40' ) GetDateTime works correctly
