implementing PHP's DateTime handling when converting timestamps from different time zones
I'm working with an scenario with PHP's `DateTime` class when I try to convert timestamps that originate from different time zones. Specifically, I have a scenario where I receive a timestamp in UTC format but need to convert it to the local time zone of the user. I implemented the following code: ```php $utcTimestamp = '2023-10-10 14:00:00'; // UTC Timestamp $dateTime = new DateTime($utcTimestamp, new DateTimeZone('UTC')); $dateTime->setTimezone(new DateTimeZone('America/New_York')); $localTimestamp = $dateTime->format('Y-m-d H:i:s'); ``` However, when I run this code, I expect the output to be `2023-10-10 10:00:00`, but instead, I'm getting `2023-10-10 14:00:00`. I also checked if daylight saving time might be affecting the conversion, but it should be accounted for with the `DateTimeZone` class in PHP 8.1. I've tried several variations, such as using `DateTimeImmutable` instead of `DateTime` to avoid side effects, but the result remains the same. I double-checked the time zone settings in my PHP configuration and ensured that the environment is correctly set up for the New York timezone with: ```php $timezone = date_default_timezone_get(); echo $timezone; // Should output 'America/New_York' ``` The output confirms that the timezone is correctly set, yet the conversion still yields an unexpected result. Can anyone guide to understand why the time conversion isn't working as intended? Am I missing something in terms of handling the time zones? Any suggestions for debugging this would be greatly appreciated!
