That is the correct operation. The manual says, "The TIMESTAMP column type provides a type that you can use to automatically mark INSERT or UPDATE operations with the current date and time. If you have multiple TIMESTAMP columns, only the first one is updated automatically.", in section 6.2.2.2. You may want to use a DATETIME column type and use the NOW() function to set it.
