Bug report

Bug description:

As proposed in #108533 the time zone was renamed but we can't simply rename it in the test cause it fails on old(?) MacOS systems. I would propose to prepend it with:

@unittest.skipUnless(os.path.exists('/usr/share/zoneinfo/Europe/Kyiv') or
                         os.path.exists('/usr/lib/zoneinfo/Europe/Kyiv'),
                         "Can't find the Olson's TZ database")

CPython versions tested on:

3.11

Operating systems tested on:

Linux
