How do you test code that uses DateTimeFormatter?

Testing code that utilizes DateTimeFormatter can be crucial for ensuring that your date and time formatting is working as expected. Here’s how you might approach writing tests for code that uses this functionality.

Here is an example in PHP demonstrating how to use DateTimeFormatter:

            $dateTime = new DateTime('2023-10-10 14:30:00');
            $formatter = DateTimeFormatter::ofPattern('yyyy-MM-dd HH:mm:ss');
            echo $dateTime->format($formatter);
            ?>
