Marking my own ticket as accepted and a release blocker because it's a bisected regression.

It's probably just a matter of skipping these tests, Windows can't use a time zone other than the system time zone.

comment:4 by Aymeric Augustin, 10 years ago

Affected tests use 'Europe/Copenhagen', which is the same as 'Europe/Paris'; that's why I didn't notice the issue.

In 9cc3371a0f45894de12d2fb60a57afd111fb9c3e:

Fixed #21756 -- Skipped two timezone-related tests on Windows.

Windows cannot use a time zone other than the default time zone.

Thanks manfre for the report.
