Centre redeveloped to be modern (6)
I believe the answer is:
recent
'be modern' is the definition.
(I've seen this before)
'centre redeveloped' is the wordplay.
'redeveloped' indicates an anagram.
'centre' is an anagram of 'RECENT'.
'to' is the link.
(Other definitions for recent that I've seen before include "Done not long ago" , "Having been done lately" , "Just gone by" , "Having happened lately" , "Happening lately" .)
