Are there any specific PHP functions or libraries that can help with summing up time intervals?

When summing up time intervals in PHP, you can use the `DateInterval` class along with the `DateTime` class to perform the calculations. By creating instances of `DateInterval` and adding them together, you can accurately sum up time intervals. 

// Define time intervals to be summed up
$interval1 = new DateInterval('PT1H30M'); // 1 hour and 30 minutes
$interval2 = new DateInterval('PT45M'); // 45 minutes

// Create a DateTime object to store the sum
$totalTime = new DateTime();
$totalTime->add($interval1);
$totalTime->add($interval2);

// Output the total time in hours and minutes
echo $totalTime->format('H:i');
