Slip out in time for show (7)
I believe the answer is:
display
'show' is the definition.
(display can mean to show or expose)
'slip out in time' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'in' is an insertion indicator.
'time' becomes 'day' (day is a kind of time).
'slip' anagrammed gives 'ispl'.
'ispl' put into 'day' is 'DISPLAY'.
'for' is the link.
(Other definitions for display that I've seen before include "Demonstrate, show" , "Place on show" , "Exhibit, show" , "Put on show" , "Showcase" .)
