What are the potential pitfalls of using timestamps in PHP for date comparisons and calculations?

One potential pitfall of using timestamps in PHP for date comparisons and calculations is that timestamps are based on the number of seconds since the Unix epoch (January 1, 1970), which can lead to inaccuracies when dealing with dates far in the past or future. To avoid this issue, it's recommended to use PHP's DateTime class, which provides more flexibility and accuracy when working with dates and times. 

// Using DateTime class for accurate date comparisons and calculations
$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');

// Calculate the difference between two dates
$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
