What are the advantages and disadvantages of using DateTime objects for setting cookie expiration dates in PHP compared to UNIX timestamps?

When setting cookie expiration dates in PHP, using DateTime objects allows for more flexibility and readability in managing dates and times compared to UNIX timestamps. However, DateTime objects require more processing power and memory compared to UNIX timestamps, which may impact performance in high-traffic applications. 

// Using DateTime objects for setting cookie expiration date
$expirationDate = new DateTime();
$expirationDate->modify('+1 day'); // Cookie expires in 1 day
setcookie('cookie_name', 'cookie_value', $expirationDate->getTimestamp());

// Using UNIX timestamps for setting cookie expiration date
$expirationTimestamp = time() + 86400; // Cookie expires in 1 day
setcookie('cookie_name', 'cookie_value', $expirationTimestamp);
