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..,,, I think conversing with you must be delightful if you take such care to be elegant as to choose to say "time enough" whenever the opportunity arises. Please do not be sad. And re the Bard, are you maybe thinking of Marvell?
Is there a message hidden here that my almost 50 years of English can not divine??
