Is there a reason why this isn't GH 38723?

typo, should be #34479, which is about the long-term behavior we want, #38723 is about ensuring that the interim behavior is internally-consistent. just updated

What is the inconsistency this is fixing? (how is it behaving differently?)

What is the inconsistency this is fixing? (how is it behaving differently?)

dti = pd.date_range("2016-01-01", periods=3)
dti2 = dti.tz_localize("UTC")

df = pd.DataFrame(dti)
df2 = pd.DataFrame(dti2)

>>> df.all()
0    True
dtype: bool

>>> df2.all()
Series([], dtype: bool)

Thanks for that example, that helps ;)
(in general, it would help if you try give a bit more context when opening PRs)

That's indeed certainly an inconsistency to fix. But quickly checking, this actually seems to have worked fine before, so might be a regression? (and thus should potentially target this for 1.2.1)

I suppose this will also enable the any/all methods on Series?
(in which case we should add tests for that)
