Time needed by French composer making journey (6)
I believe the answer is:
travel
'journey' is the definition.
('travel' can be a synonym of 'journey')
'time needed by french composer' is the wordplay.
'time' becomes 't'.
'needed by' says to put letters next to each other.
'french composer' becomes 'ravel' (I've seen this before).
't'+'ravel'='TRAVEL'
'making' is the link.
(Other definitions for travel that I've seen before include "Pass" , "Voyage" , "Go on a trip" , "Move from one place to another" , "Journey from one place to another" .)
