What are the potential pitfalls of using timestamps for time-based operations in PHP?

One potential pitfall of using timestamps for time-based operations in PHP is that timestamps are based on the number of seconds since the Unix epoch, which may not accurately represent time in certain scenarios (such as leap years or daylight saving time changes). To address this issue, it is recommended to use PHP's DateTime class, which provides more flexibility and accuracy for time-based operations. 

// Using DateTime class to handle time-based operations
$dateTime = new DateTime();
$dateTime->setTimestamp($timestamp); // Set timestamp value
$dateTime->modify('+1 day'); // Add one day to the timestamp
$newTimestamp = $dateTime->getTimestamp(); // Get the updated timestamp value
