> add supers?


Assuming by two "foundations", you mean you have 2 deeps or hive bodies, if
the frames are drawn out and are being filled, the bees will have stores for
the winter.

Generally, you add supers to get honey.  Bees will not draw new foundation
well unless there is a nectar flow or you are feeding heavily.  I would
recommend waiting until next spring and add them in late March or when you
get maple, clover or dandelion bloom.

 ...morning, evening or afternoon?


Mid-day can be best because foragers are out and there are fewer bees in the
hive.  If you have had a dry spell and the queen has shut down so there are
fewer bees, any time can be good.  The best time is when you have time to do
a good inspection and not feel rushed.
