Times reporter's shock (4)
I believe the answer is:
days
'times' is the definition.
(day is a unit of time)
'reporter's shock' is the wordplay.
'reporter's' indicates a 'sounds like' (homophone) clue (report can mean to speak something aloud).
'shock' becomes 'daze' (synonyms).
'daze' sounds like 'DAYS'.
(Other definitions for days that I've seen before include "Twenty four hour periods" , "See 7 and 18" , "` `They are not long, the .... of wine and roses' ' (Dowson)" , "Time period(s)" , "Sun, Mon, Tues, ..." .)
