As such, the problem will not be addressed in older versions. Please migrate to PHP 7 as soon as possible. ------------------------------------------------------------------------ [2018-01-19 16:01:27] wandersonwhcr at gmail dot com Description: ------------ According to PHP Manual, DateTime class and strtotime functions use relative date and time formats. http://php.net/manual/en/datetime.formats.relative.php But using certain relative format in both classes, the result are not the same. Only PHP 5.6 generates the problem. With PHP >=7.0, the outputs are the same. Test script: --------------- <?php echo date('c') . PHP_EOL; // Current Date and Time $relative = 'first day of next month midnight -1 second'; echo date('c', (new DateTime($relative))->getTimestamp()) . PHP_EOL; echo date('c', strtotime($relative)) . PHP_EOL; ?> Expected result: ---------------- 2018-01-19T13:51:58-02:00 2018-01-31T23:59:59-02:00 2018-01-31T23:59:59-02:00 Actual result: -------------- 2018-01-19T13:51:58-02:00 2018-01-01T23:59:59-02:00 2018-01-31T23:59:59-02:00 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75849&edit=1
