Time of confusion spoken of (4)
I believe the answer is:
days
'time' is the definition.
(thesaurus)
'confusion spoken of' is the wordplay.
'confusion' becomes 'daze' (daze is a kind of confusion).
'spoken of' indicates a 'sounds like' (homophone) clue.
'daze' sounds like 'DAYS'.
'of' acts as a link.
(Other definitions for days that I've seen before include "Sevenths of a week" , "Time period(s)" , "` `They are not long, the .... of wine and roses' ' (Dowson)" , "Periods of 24 hours" , "Periods (of week)" .)
