Time everyone overturned raw conflict (6,5,3)

I believe the answer is:

second world war

'conflict' is the definition.
(I've seen this before)

'time everyone overturned raw' is the wordplay.
'time' becomes 'second' (unit of time).
'everyone' becomes 'world' (I've seen this before).
'overturned' says the letters should be written in reverse.
'raw' back-to-front is 'war'.
'second'+'world'+'war'='SECOND WORLD WAR'

(Another definition for second world war that I've seen is " conflict".)

I've seen this clue in The Daily Express.
