I think either is possible, but enough time is more usual. I think time enough is an example of inversion (change in the normal structure of a phrase) that is done for effect. Example:
What say you, teacher?
- There'll be time enough for countin' when the dealin's done.
It is not possible to be wrong on this poll and I would dearly love to know why this very enigmatic phrasing was chosen to teach English learners and what was the intention of the lesson.enough time: I voted...and I was wrong..
My thoughts are that this will be an ephemeral discourse.
Is there a message hidden here that my almost 50 years of English can not divine??
