Typo checks in core.ops

            elif (isinstance(ovalues, datetime.datetime) and
                  hasattr(ovalues, 'tzinfo')):

Is that hasattr(ovalues, 'tzinfo') supposed to be ovalues.tzinfo is not None?

I can't tell ATM, so change it and find out 😄

do you have an example of something that hits this? I would guess that we have other lines of code which work-around (so this is a no-op).

do you have an example of something that hits this?

pd.date_range('2016-01-01', periods=3).to_series() - pd.Timestamp.now() hits it.
