Confucian text about time is causing irritation (7)
I believe the answer is:
itching
'irritation' is the definition.
'confucian text about time' is the wordplay.
'confucian text' becomes 'iching' (I Ching is an ancient Chinese text).
'about' indicates putting letters inside.
'time' becomes 't' (abbreviation).
'iching' enclosing 't' is 'ITCHING'.
'is causing' is the link.
(Other definitions for itching that I've seen before include "It causes a desire to scratch" , "Consumed with curiosity" , "Having an unpleasant skin sensation" , "irritating" , "Having teasing desire" .)
