How can PHP developers ensure their code accounts for daylight saving time changes when working with time zones?

When working with time zones in PHP, developers can ensure their code accounts for daylight saving time changes by using the DateTime class and setting the time zone appropriately. By using the DateTimeZone class and adjusting for daylight saving time with the setTransitionRules() method, developers can accurately handle time zone changes. 

$date = new DateTime('now', new DateTimeZone('America/New_York'));
$date->setTimezone(new DateTimeZone('America/New_York'));
echo $date->format('Y-m-d H:i:s');
