Time of day for smoothing things out (7)
I believe the answer is:
evening
This clue could be a double definition.
'time of day' is the first definition.
(I've seen this before)
'smoothing things out' is the second definition.
'evening' can be an answer for 'smoothing' (as in making something even). I'm unsure of the 'things out' bit.
'for' is the link.
Can you help me to learn more?
(Other definitions for evening that I've seen before include "late party" , "Making flat" , "Late time of day" , "Hours before bedtime" , "Early night" .)
