Turn aside and declare time (5)
I believe the answer is:
avert
'turn aside' is the definition.
(I've seen this before)
'declare time' is the wordplay.
'declare' becomes 'aver' (averring is a kind of declaring).
'time' becomes 't' (abbreviation).
'aver'+'t'='AVERT'
'and' acts as a link.
(Other definitions for avert that I've seen before include "Ward off (bad event)" , "Prevent from happening" , "Deflect away" , "Turn aside, perhaps gaze" , "Turn away (ones eyes)" .)
