C # MYSQL connection time Question & quot; 0000-00-00 & quot;

The data volume displayed when I connect to the MYSQL database today is less than that of the database. Tracking shows that the time format allowed by MYSQL is different from that allowed by MSSQL.
 
MySqlConnection myconn = new MySqlConnection (
"Server = 192.168.1.99; uid = php; pwd = enamephp; database = db_ename;
Charset = utf8; Allow Zero Datetime = True ");
Myconn. Open ();
MySqlCommand myNamecmd = new MySqlCommand ("set names utf8", myconn );
MyNamecmd. ExecuteNonQuery ();
 
Charset = utf8; Allow Zero Datetime = True // sets the connection encoding: UTF8, followed by the time setting
