Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This turned out to be not a bug at all. 2012-10-21 00:00 in the Brazil/East zone does not exist: Brazil/East Sun Oct 21 02:59:59 2012 UT = Sat Oct 20 23:59:59 2012 -03 isdst=0 gmtoff=-10800 Brazil/East Sun Oct 21 03:00:00 2012 UT = Sun Oct 21 01:00:00 2012 -02 isdst=1 gmtoff=-7200 As Oct 20 23:59:59 is followed by Oct 01:00:00. The result therefore is not a full day, but instead 23 hours: $ cat /tmp/bug60900.phpt <?php date_default_timezone_set("Brazil/East"); $a = new DateTime('2012-10-19'); $b = new DateTime('2012-10-22'); $interval = $a->diff($b); echo $interval->format('%dD %hH %mM'), "\n"; $a = new DateTime('2012-10-20'); $b = new DateTime('2012-10-22'); $interval = $a->diff($b); echo $interval->format('%dD %hH %mM'), "\n"; $a = new DateTime('2012-10-21'); $b = new DateTime('2012-10-22'); $interval = $a->diff($b); echo $interval->format('%dD %hH %mM'), "\n"; Produces: 3D 0H 0M 2D 0H 0M 0D 23H 0M Previous Comments: ------------------------------------------------------------------------ [2021-03-31 16:35:11] cmb@php.net For reference: <https://3v4l.org/P5D2u>. ------------------------------------------------------------------------ [2021-03-31 16:34:23] cmb@php.net Related To: Bug #80913 ------------------------------------------------------------------------ [2012-02-03 14:12:17] derick@php.net This is a bug, it should show 1. ------------------------------------------------------------------------ [2012-02-03 14:10:36] robertosuursoo at yahoo dot com dot br The function call worked perfectly and solved the problem! date_default_timezone_set('UTC'); Thank you very much! ------------------------------------------------------------------------ [2012-02-03 13:43:32] robertosuursoo at yahoo dot com dot br Thanks a lot! ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
