Shock announcement of Times (4)
I believe the answer is:
daze
'shock' is the definition.
(I know that shock can be written as daze)
'announcement of times' is the wordplay.
'announcement of' indicates a 'sounds like' (homophone) clue.
'times' becomes 'days' (day is a unit of time).
'days' sounds like 'DAZE'.
(Other definitions for daze that I've seen before include "bowl over" , "Stun using adze" , "Benumb" , "can turn out to be stunning?" , "Confused state unable to think clearly" .)
