It's nothing to be in credit for the month (7)

I believe the answer is:

october

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

But I can't explain it at all! Could you help me understand?

(Other definitions for october that I've seen before include "Bore cot out at this time" , "Tenth month" , "Would need cot robe at this time of the year" , "Russian Revolution month" , "Bore cot in autumn" .)

I've seen this clue in The Sun.
