I believe the answer is:

in good time

I'm a little stuck... Click here to teach me more about this clue!

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

I can't explain the remainder of the clue.

(Other definitions for in good time that I've seen before include "Quickly" , "Without risk of being late" , "How the drummer should play" , "Certainly not late" , "Quite early enough" .)

I've seen this clue in The Irish Independent.
