Need little time? (8)
I believe the answer is:
shortage
'need' is the definition.
(shortage is a kind of need)
'little time?' is the wordplay.
'little' becomes 'short' ('short' can be similar in meaning to 'little').
'time?' becomes 'age' (age is a kind of time**).
'short'+'age'='SHORTAGE'
(Other definitions for shortage that I've seen before include "Want" , "Dearth, lack" , "Need" , "Scarcity" , "Lack, deficiency" .)
