<?php // Example of common mistakes $dateTime = new DateTime('2023-10-15 12:00:00', new DateTimeZone('America/New_York')); // Mistake: Using ZoneOffset instead of ZoneId $zoneOffset = DateTimeZone::createFromFormat('P', '-05:00'); $dateTime->setTimezone($zoneOffset); // Incorrect usage echo $dateTime->format('Y-m-d H:i:s'); ?>
