Time to change the piece in the paper (4)
I believe the answer is:
item
'piece in the paper' is the definition.
(I've seen this in another clue)
'time to change' is the wordplay.
'to change' indicates anagramming the letters.
'time' with letters rearranged gives 'ITEM'.
'the' acts as a link.
(Other definitions for item that I've seen before include "Book-keeping entry" , "Single article on a list" , "Particular" , "Loving couple" , "newspaper article" .)
