Add ... "Time for ancillary part!" (9)

I believe the answer is:

appendage

I'm a little stuck... Click here to teach me more about this clue!

'ancillary part' is the definition.
'appendage' can be an answer for 'part' (appendage is a kind of part). I'm not certain of the 'ancillary' bit.

'add time' is the wordplay.
'add' becomes 'append' (synonyms).
'time' becomes 'age' (an age is a period of time).
'append'+'age'='APPENDAGE'

'for' is the link.

Can you help me to learn more?

(Other definitions for appendage that I've seen before include "It hangs on" , "Attached item" , "An outgrowth" , "Addendum" , "Something attached to a larger thing" .)

I've seen this clue in the Sydney Morning Herald.
