To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. I can't reproduce this with PHP 7.2.10, 7.2.35, 7.3.25, nor 8.0.3: 8.0.4-dev derick@gargleblaster:~/dev/php/php-src.git$ php -ddate.timezone=Europe/Berlin <?php $date = date_create('2019-01-31 02:00:12'); date_add($date, date_interval_create_from_date_string('2 months')); echo date_format($date, 'Y-m-d H:i:s'); ?> 2019-03-31 03:00:12 ------------------------------------------------------------------------ [2021-03-28 07:34:48] r dot schuil at gmail dot com Still not fixed? ------------------------------------------------------------------------ [2019-03-24 09:43:11] r dot schuil at gmail dot com $ php -r 'echo date_default_timezone_get(); Europe/Berlin ------------------------------------------------------------------------ [2019-03-24 09:37:51] requinix@php.net What does date_default_timezone_get() return? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
