Satisfied dates are wrong (5)
I believe the answer is:
sated
'satisfied' is the definition.
(I've seen this before)
'dates are wrong' is the wordplay.
'are wrong' indicates anagramming the letters.
'dates' anagrammed gives 'SATED'.
(Other definitions for sated that I've seen before include "given more than enough" , "with no empty spaces?" , "Stuffed, having had a surfeit" , "fully indulged" , "Indulged to the full" .)
