Unfortunately you are not using a current version of PHP -- the problem might already be fixed. Please download a new PHP version from http://www.php.net/downloads.php If you are able to reproduce the bug with one of the latest versions of PHP, please change the PHP version on this bug report to the version you tested and change the status back to "Open". Again, thank you for your continued support of PHP. Looks from the 3v4l link that that got fixed in 7.2.12 already.

Start: 2015-08-31 00:00:00.000001 End: 2015-09-01 00:00:00.000000 The diff object returned by the method DateTime::diff() for these dates reports that a whole day has been elapsed since the start date. As evidenced, such result is wrong since 1 microsecond is missing in the interval to complete a full day. In an addition, the result of the number of microseconds is expected to be positive, as all the units do. However, in this case, the result is negative. Test script: --------------- https://3v4l.org/6INks Expected result: ---------------- Years: 0 Days: 0 Total days: 0 Months: 0 Hours: 0 Minutes: 0 Seconds: 0 Microseconds: 1.0E-6 Actual result: -------------- Years: 0 Days: 1 Total days: 1 Months: 0 Hours: 0 Minutes: 0 Seconds: 0 Microseconds: 1.0E-6 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75855&edit=1
