Group of nine getting no part on time (5)
I believe the answer is:
nonet
'group of nine' is the definition.
(I've seen this before)
'no part on time' is the wordplay.
'no part' becomes 'none' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other) (in a down clue, letters appear on others).
'time' becomes 't' (abbreviation).
'none'+'t'='NONET'
'getting' is the link.
(Other definitions for nonet that I've seen before include "Musical composition -- tonne (anag)" , "Band of nine?" , "Musical work for a set number of performers" , "Ennead" , "Group of nine musicians" .)
