°Missing a TZ assertion, but I don't remember what happens by default. Zulu time? I'd hope so, but that reinforces my point.
I would also read the documentation. In the given example, for example, you don't know if the desired fixed format "YYYY-MM-DD" might depend on some locale setting and only works because you happen to have the correct one in that test console.
