For Dutch town, took flight back ahead of time (5)
I believe the answer is:
delft
'for dutch town' is the definition.
(I've seen this before)
'took flight back ahead of time' is the wordplay.
'took flight' becomes 'fled' ('flee' can be a synonym of 'take flight').
'back' says the letters should be written backwards.
'ahead of time' becomes 't' (I've seen this in other clues).
'fled' backwards is 'delf'.
'delf'+'t'='DELFT'
(Other definitions for delft that I've seen before include "cups, etc" , "Style of earthenware" , "Dutch blue and white glazed earthenware" , "Dutch pottery style" , "Netherlands town famed for pottery" .)
