  • MySQL DATETIME vs TIMESTAMP and the year 2038

    Judging from MySQL documentation at https://dev.mysql.com/doc/refman/8.0/en/datetime.html, it sounds best to use DATETIME rather than TIMESTAMP if you want your database to be future proof. After all 2038 is only 18+ years away. The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values ...
