For the moment when a mile off ... (9)
I believe the answer is:
meanwhile
'for the moment' is the definition.
(I've seen this before)
'when a mile off' is the wordplay.
'off' is an anagram indicator.
'when'+'a'+'mile'='whenamile'
'whenamile' anagrammed gives 'MEANWHILE'.
(Other definitions for meanwhile that I've seen before include "In the interim" , "On the other hand" , "In the intervening time" , "For the moment" , "simultaneously" .)
