I'm given time to create public persona (5)
I believe the answer is:
image
'public persona' is the definition.
(I've seen this in another clue)
'i'm given time' is the wordplay.
'given' is a charade indicator (letters next to each other).
'time' becomes 'age' (an age is a period of time).
'im'+'age'='IMAGE'
'to create' acts as a link.
(Other definitions for image that I've seen before include "personality" , "Likeness, might be spitting" , "Likeness, could be spitting" , "Likeness; metaphor" , "Picture (involving one letter change from 10)" .)
