Are there any built-in PHP functions or libraries that can assist with timestamp manipulation and calculations?

When working with timestamps in PHP, you can use built-in functions in the `DateTime` class to manipulate and perform calculations on timestamps. This class provides a wide range of methods for adding or subtracting time intervals, formatting timestamps, and comparing dates. By utilizing the `DateTime` class, you can easily handle timestamp manipulation and calculations in PHP. 

// Create a DateTime object with the current timestamp
$timestamp = new DateTime();

// Add 1 day to the timestamp
$timestamp->modify('+1 day');

// Format the timestamp in a specific format
$formattedTimestamp = $timestamp->format('Y-m-d H:i:s');

echo $formattedTimestamp;
