Time of confusion, we hear (4)
I believe the answer is:
days
'time' is the definition.
(day is a unit of time)
'confusion we hear' is the wordplay.
'confusion' becomes 'daze' (daze is a kind of confusion).
'we hear' indicates a 'sounds like' (homophone) clue.
'daze' sounds like 'DAYS'.
'of' is the link.
(Other definitions for days that I've seen before include "Sun, Mon, Tues, ..." , "See 25" , "Units of time" , "24-hour periods" , "Periods (of week)" .)
