Time of day for getting level (7)
I believe the answer is:
evening
This clue is a triple definition!
'time' is the first definition.
(time of day)
'of' acts as a link.
'day' is the second definition.
(evening is a kind of day)
'for' is a link.
'getting level' is the third definition.
(making even or level)
(Other definitions for evening that I've seen before include "somewhat late in the day" , "Pressing - time of day" , "Levelling the score" , "Time of falling light" , "after dark?" .)
