What are the potential pitfalls of using timestamp and time data types in PHP when storing and querying date and time values in a database?

One potential pitfall of using timestamp and time data types in PHP when storing and querying date and time values in a database is that timestamps are stored as integers representing the number of seconds since the Unix Epoch, which can lead to unexpected results when working with dates far in the past or future. To avoid this issue, it is recommended to use the DATETIME data type in MySQL, which stores dates and times in the format 'YYYY-MM-DD HH:MM:SS'. 

// Using DATETIME data type in MySQL to store date and time values
$sql = "CREATE TABLE events (
    id INT AUTO_INCREMENT PRIMARY KEY,
    event_name VARCHAR(255),
    event_date DATETIME
)";
