Repeating it will take time to get into shape (9)

Ross

I believe the answer is:

iteration

'repeating' is the definition.
(I know that iteration is a type of repeating)

'it will take time to get into shape' is the wordplay.
'will take' says to put letters next to each other.
'time' becomes 'era' (an era is a period of time).
'to get' indicates putting letters inside.
'shape' is an anagram indicator.
'into' anagrammed gives 'tion'.
'era' placed inside 'tion' is 'eration'.
'it'+'eration'='ITERATION'

(Other definitions for iteration that I've seen before include "Reprise" , "Repeats" , "Repeating" , "Repeated performing" , "Repetition" .)

I've seen this clue in the Evening Standard and The Telegraph.
