What should have happened instead?:
Tests should passed, but negativ time correction is applied as positive correction.

Software version (skip for WMF-hosted wikis like Wikipedia): master (tests via https://gerrit.wikimedia.org/r/c/mediawiki/core/+/976316)

The test is calling Language::userAdjust, which calls DateTime::modify with "+{$minDiff} minutes" where $minDiff is the time correction to apply.
For negative correction this results in +-120 minutes, it seems the - is ignored in php8.2

DateTime::modify depends on strtotime to pass the modifier, but it seems that is broken:

# php -v
PHP 8.2.3 (cli) (built: Feb 14 2023 09:55:52) (ZTS Visual C++ 2019 x64)

# php maintenance\eval.php
> echo strtotime( "@1000000000 +120 minutes" );
1000007200
> echo strtotime( "@1000000000 -120 minutes" );
999992800
> echo strtotime( "@1000000000 +-120 minutes" );
1000007200
# php -v
PHP 8.1.8 (cli) (built: Jul  5 2022 23:04:29) (ZTS Visual C++ 2019 x64)

# php maintenance\eval.php
> echo strtotime( "@1000000000 +120 minutes" );
1000007200
> echo strtotime( "@1000000000 -120 minutes" );
999992800
> echo strtotime( "@1000000000 +-120 minutes" );
999992800

number symbols in relative formats no longer accept multiple signs, e.g. +-2

Not sure about impact about all the strtotime in the code and possible values stored in the database.

Umherirrender renamed this task from TimeAdjustTest::testUserAdjust failure under php8.2 (strtotime handling of +- changed) to TimeAdjustTest::testUserAdjust failure under php8.2 (strtotime handling of multiple signs changed).Nov 22 2023, 8:35 PM
