           Summary: [JSC] Some JSC stress tests are dependent on the
                    machine time zone.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org

I have noticed that some of the JSC stress tests fail if your timezone is not PDT (At least on the GTK port, didn't tested other ports).

They pass all OK if your timezone is PDT:

$ export TZ="US/Pacific"
$ Tools/Scripts/run-javascriptcore-tests --release --gtk --no-build
[...]
9887/9887         

Results for JSC stress tests:
    0 failures found.
    OK.


But some fail if you have another timezone:

$ export TZ="Europe/Madrid"
$ Tools/Scripts/run-javascriptcore-tests --release --gtk --no-build
[...]
9887/9887 (failed 4)         

** The following JSC stress test failures have been introduced:
    mozilla-tests.yaml/ecma_3/Date/15.9.5.6.js.mozilla
    mozilla-tests.yaml/ecma_3/Date/15.9.5.6.js.mozilla-baseline
    mozilla-tests.yaml/ecma_3/Date/15.9.5.6.js.mozilla-dfg-eager-no-cjit-validate-phases
    mozilla-tests.yaml/ecma_3/Date/15.9.5.6.js.mozilla-llint

Results for JSC stress tests:
    4 failures found.



To workaround this, maybe we can just export the environment variable TZ to US/Pacific on the script run-javascriptcore-tests ?
