What are the best practices for handling timestamps beyond the limitations of strtotime in PHP?

When handling timestamps beyond the limitations of strtotime in PHP, a best practice is to use the DateTime class, which offers more flexibility and accuracy in parsing and manipulating dates and times.

// Example of handling timestamps beyond strtotime limitations using DateTime class
$dateString = '2022-12-31 23:59:59';
$dateTime = DateTime::createFromFormat('Y-m-d H:i:s', $dateString);
echo $dateTime->format('Y-m-d H:i:s');
