'at this point?' is the definition.
(I've seen this in another clue)

'out of whiskey' is the wordplay.
'out of' becomes 'no' (I can't explain this - if you can you should give a lot more credence to this answer).
'whiskey' becomes 'W' (phonetic alphabet: alpha, bravo, charlie etc.).
'no'+'w'='NOW'

(Other definitions for now that I've seen before include "At the present time" , "At this moment in time" , "The present moment" , "Today" , "straight away" .)
