Give out wrong time (4)
I believe the answer is:
emit
'give out' is the definition.
(synonyms)
'wrong time' is the wordplay.
'wrong' indicates an anagram.
'time' anagrammed gives 'EMIT'.
(Other definitions for emit that I've seen before include "Sent" , "Make audible sounds" , "shed" , "'Give off, odour say (4)'" , "Give out (eg light)" .)
