In what scenarios would it be beneficial to use DateTimeZone in PHP for date calculations?

When working with date and time calculations in PHP, it is beneficial to use DateTimeZone to ensure accurate results, especially when dealing with time zones. DateTimeZone allows you to specify the time zone for your date calculations, ensuring that the calculations are performed correctly regardless of the server's default time zone setting.

// Create a DateTime object with a specific time zone
$date = new DateTime('now', new DateTimeZone('America/New_York'));

// Perform date calculations with the DateTime object
$date->modify('+1 day');

// Output the modified date in the specified time zone
echo $date->format('Y-m-d H:i:s');
