What potential pitfalls should be considered when storing dates in UNIX timestamp format in a PHP application?

When storing dates in UNIX timestamp format in a PHP application, one potential pitfall to consider is the limitation of the UNIX timestamp to dates between 1970 and 2038. To address this issue, you can use PHP's DateTime class to handle dates beyond this range. 

// Storing a date in UNIX timestamp format
$timestamp = strtotime('2039-01-01');

// Using DateTime class to handle dates beyond 2038
$date = new DateTime('2039-01-01');
$timestamp = $date->getTimestamp();
