Question

$opening_date = '2020-01-01T00:00:00+08:00'         
$opening_date = date('Y-m-d 00:00:00', strtotime($opening_date));

PHP 5.6 result

2020-01-01 00:00:00

PHP 8.0 result

2019-12-31 00:00:00

Hi, I'm doing date converting with different version but have no idea why the code is same but result is different. The expected result shall be 2020-01-01 00:00:00 but in PHP8.0 it minus 1 day. Is there any solution about this?

Can't [reproduce](https://3v4l.org/BJJV2) your error, is this all the code? can you make sure the timezone setting are the same on both version. — catcon, Mar 25 '21 at 04:45

This is not the issue related to version of PHP. I think you have not defined the timezone correctly.

This is the code that I have written. (Assuming New_York as timezone)

<?php
$timezone = "America/New_York";
$opening_date = '2020-01-01T00:00:00+08:00';
echo $opening_date = date('Y-m-d 00:00:00', strtotime($opening_date));
?>

& in both versions of PHP, It is showing me the same output.
