What are some common pitfalls when trying to add up time values in PHP and MySQL?

One common pitfall when adding up time values in PHP and MySQL is not converting the time values to a consistent format before performing calculations. To solve this, it is important to convert all time values to a common format, such as seconds, before adding them together. This ensures accurate results when calculating total time durations. 

// Convert time values to seconds before adding them together
$time1 = strtotime('10:30:00');
$time2 = strtotime('02:45:00');

$totalTimeInSeconds = $time1 + $time2;

// Convert total time back to HH:MM:SS format
$totalTime = gmdate("H:i:s", $totalTimeInSeconds);

echo "Total time: " . $totalTime;
