Are there any specific PHP functions or libraries that can simplify timestamp calculations?

When working with timestamps in PHP, it can be helpful to use the built-in DateTime class along with its methods to simplify timestamp calculations. The DateTime class provides various methods for adding or subtracting time intervals from a given timestamp, making date and time manipulation much easier. 

// Example of using DateTime class to simplify timestamp calculations

$timestamp = time(); // Get the current timestamp
$date = new DateTime();
$date->setTimestamp($timestamp);

// Adding 1 day to the timestamp
$date->add(new DateInterval('P1D'));

echo $date->format('Y-m-d H:i:s'); // Output the new timestamp with added 1 day
