How can PHP developers ensure that their code functions correctly with date calculations over time?

When working with date calculations in PHP, it's important for developers to account for time zones and daylight saving time changes to ensure accuracy over time. One way to achieve this is by using PHP's DateTime class along with setting the appropriate time zone. This allows for consistent and reliable date calculations regardless of the server's default settings. 

// Set the default time zone to ensure accurate date calculations
date_default_timezone_set('UTC');

// Create a new DateTime object with the desired date and time
$date = new DateTime('2022-12-31 23:59:59');

// Perform date calculations as needed
$date->modify('+1 day');

// Output the updated date
echo $date->format('Y-m-d H:i:s');
