Time in unsophisticated local (6)
I believe the answer is:
native
'local' is the definition.
('native' can be similar in meaning to 'local')
'time in unsophisticated' is the wordplay.
'time' becomes 't'.
'in' means one lot of letters goes inside another.
'unsophisticated' becomes 'naive' ('naive' can be a synonym of 'unsophisticated').
't' going into 'naive' is 'NATIVE'.
(Other definitions for native that I've seen before include "Belonging to one by birth" , "Local inhabitant" , "One born in a certain place" , "Endemic - aborigine" , "Resident" .)
