      As reported upstream the zic parsing code of libstdc++ makes some mistakes, using UTC times where it should use zone times, in determining the times of transitions. This ticket is here mainly to keep track of the upstream ticket and be referenced by each QEXPECT_FAIL() related to that issue. Hopefully these last can have their #if-ery tweaked once it's fixed upstream and later be removed once libstdc++ version 14 is ancient history.

      We'll also need to update qtbase/src/corelib/doc/src/cpp20-overview.qdoc's comments on feature timezone_tzdb being experimental, once this is resolved.
