What are the potential issues with managing time intervals in PHP, especially when transitioning between days?

One potential issue when managing time intervals in PHP, especially when transitioning between days, is handling the change in date properly. To solve this, you can use the DateTime class in PHP, which provides convenient methods for working with dates and times. By using this class, you can accurately calculate time intervals that span across multiple days. 

// Example of managing time intervals in PHP using DateTime class

$startTime = new DateTime('2022-01-01 23:00:00');
$endTime = new DateTime('2022-01-02 01:00:00');

$interval = $startTime->diff($endTime);

echo $interval->format('%H:%I:%S'); // Output: 02:00:00
