In terms of performance and efficiency, is it better to store date and time data in MySQL as INT in UNIX format or as DATETIME?

Storing date and time data as INT in UNIX format can be more efficient in terms of performance as it requires less storage space and can be faster to query. However, using DATETIME format allows for easier manipulation and readability of the data. The choice between the two should depend on the specific requirements of the application, weighing the trade-offs between performance and ease of use. 

// Storing date and time data as INT in UNIX format
$timestamp = time();
$query = "INSERT INTO table_name (timestamp_column) VALUES ($timestamp)";

// Storing date and time data as DATETIME
$datetime = date('Y-m-d H:i:s');
$query = "INSERT INTO table_name (datetime_column) VALUES ('$datetime')";
