Up-to-date part of leisure centre (6)
I believe the answer is:
recent
'up-to-date' is the definition.
(I've seen this before)
'part of leisure centre' is the wordplay.
'part of' says the answer is hidden in the clue.
'RECENT' is hidden in the letters of 'leisure centre'.
(Other definitions for recent that I've seen before include "Shortly before the present" , "Having happened not long ago" , "In the near past, not long ago" , "Fresh, modern" , "Occurring not long ago" .)
