New JSC failures just started after <https://trac.webkit.org/changeset/180884>. This makes no sense, as these tests are unrelated to the GTK-only file that was modified in that change. The failing tests are: ** The following JSC stress test failures have been introduced: mozilla-tests.yaml/ecma/Date/15.9.5.8.js.mozilla mozilla-tests.yaml/ecma/Date/15.9.5.8.js.mozilla-baseline mozilla-tests.yaml/ecma/Date/15.9.5.8.js.mozilla-dfg-eager-no-cjit-validate-phases mozilla-tests.yaml/ecma/Date/15.9.5.8.js.mozilla-llint Could we be hitting a time zone problem? The Daylight Saving Time change isn't until next week.
These are likely failing because the test doesn't properly handle daylight savings time changes.
