Time for making uniform (7)
I believe the answer is:
evening
I believe this clue is a double definition.
'time' is the first definition.
(time of day)
'making uniform' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for evening that I've seen before include "Making uniform" , "time for putting feet up?" , "Ironing" , "twilight" , "Subject of nocturne" .)
