Time of confusion, say (4)
I believe the answer is:
days
'time' is the definition.
(thesaurus)
'confusion say' is the wordplay.
'confusion' becomes 'daze' (daze is a kind of confusion).
'say' indicates a 'sounds like' (homophone) clue.
'daze' is a homophone of 'DAYS'.
'of' acts as a link.
(Other definitions for days that I've seen before include "Twenty four-hour periods" , "Twenty four hour periods" , "Periods (of week)" , "Time period(s)" , "24-hour periods" .)
