Gave a man the wrong date (7)
I believe the answer is:
donated
'gave' is the definition.
(donating is a kind of giving)
'a man the wrong date' is the wordplay.
'a man' becomes 'don' (Don is an example).
'the wrong' indicates anagramming the letters.
'date' anagrammed gives 'ated'.
'don'+'ated'='DONATED'
(Other definitions for donated that I've seen before include "Given" , "Presented" , "Gave" .)
