# This one is useful because sometimes the bundled time zone database can
# behave differently than the system time zone database depending on the
# inputs. For example, the bundled database uses as few transitions as possible
# (this is tzdb's "slim" data model) and thus relies more heavily on POSIX
# time zone strings. So if there's a bug in POSIX time zone handling, you're
# likely to see it with the bundled database while missing it completely with
# the system database.

# We test core-only mode specially. Sadly, in core-only mode, error messages
# are quite a bit worse. And this wreaks havoc with Jiff's snapshot tests on
# error messages. We could `cfg` all of them, but that's a huge pain and it's
# not clear that it's worth it.
#
# Since we use snapshot tests for more than error messages, this technique also
# risks accidentally passing a test that doesn't involve error messages. Sigh.
# We accept this risk because this still runs a lot of tests, and the tests
# that aren't covered are run in other configurations. Still, it's not ideal.
