How can developers ensure that PHP automatically adjusts for daylight saving time changes when working with different time zones?

Developers can ensure that PHP automatically adjusts for daylight saving time changes when working with different time zones by setting the appropriate time zone using the `date_default_timezone_set()` function. This function should be called at the beginning of the script to ensure that PHP is aware of the correct time zone and can handle daylight saving time changes accordingly. 

// Set the default time zone to the desired location
date_default_timezone_set('America/New_York');

// Now PHP will automatically adjust for daylight saving time changes
$current_time = date('Y-m-d H:i:s');
echo $current_time;
