What is the difference between the MySQL DATETIME and TIMESTAMP data types?

Both data types store data in the format "YYYY-MM-DDHH:MM:SS" and include date and time. Despite these similarities, they have the following differences - Range - The datetime data type supports dates and times between 1000-01-0100:00:00 and 9999-12-3123:59:59. However, the timestamp data type supports dates and times between "1970-01-0100:00:01" and "2038-01-1908:44:07". Size - The datetime requires 5 bytes plus 3 additional bytes for fractional seconds data storage. On the other hand, the timestamp data type requires 4 bytes plus 3 additional bytes for fractional seconds data
