Previous Comments: ------------------------------------------------------------------------ [2017-05-02 20:06:00] andrew dot nester dot dev at gmail dot com Thanks Derick! gonna rework my pull request ------------------------------------------------------------------------ [2017-05-02 12:34:14] derick@php.net Andrew, it might look fixed for you because you have a different timezone with different DST rules configured. ------------------------------------------------------------------------ [2017-05-02 12:12:51] andrew dot nester dot dev at gmail dot com thanks for reporting this issue! I tried to reproduce it on latest 7.1 build (7.1.6-dev) - working good. but anyway I decided to add test to prove that it works as expected (see my PR) ------------------------------------------------------------------------ [2017-05-02 11:04:36] hrovira at seocom dot es Obviously, expected and actual results are switched :( ------------------------------------------------------------------------ [2017-05-02 11:03:12] hrovira at seocom dot es Description: ------------ DateTime::diff generates different DateInterval results depending on the order, even though $absolute param is set to true. date1->diff(date2, true) is different than date2->diff(date1, true). Please, see test script. Test script: --------------- <?php $date1 = date_create("2014-11-01 00:00:00"); $date2 = date_create("2017-05-01 04:00:00"); $diff1 = $date2->diff($date1, true); $diff2 = $date1->diff($date2, true); echo $diff1->m .' months, '.$diff1->d. ' days'; // outputs: 6 months, 0 days echo $diff2->m .' months, '.$diff2->d. ' days'; // outputs: 5 months, 30 days Expected result: ---------------- 6 months, 0 days 5 months, 30 days Actual result: -------------- 6 months, 0 days 6 months, 0 days ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74529&edit=1
