Issue of American magazine sent back (4)
I believe the answer is:
emit
'issue' is the definition.
(thesaurus)
'american magazine sent back' is the wordplay.
'american magazine' becomes 'time'.
'sent back' shows that the letters should be reversed in order.
'time' back-to-front is 'EMIT'.
'of' is the link.
(Other definitions for emit that I've seen before include "Produce and discharge" , "Let out" , "Send forth" , "Sent" , "Make audible sounds" .)
