Subject: [PATCH] Fix tests with Europe/Amsterdam pre-1970 time on tzdata
 version 2022b.

The Time Zone Database (tzdata) changed the pre-1970 timestamps in some zones
including Europe/Amsterdam on tzdata version 2022b or later.
See <https://github.com/eggert/tz/commit/35fa37fbbb152f5dbed4fd5edfdc968e3584fe12>.

The tzdata RPM package maintainer on Fedora project suggested changing the Ruby
test, because the change is intentional.
See <https://bugzilla.redhat.com/show_bug.cgi?id=2118259#c1>.

We use post-1970 time test data to simplify the test.
