Crossword Genius

At unspecified time, not enough to raise capital? (3,3)

Ross

I believe the answer is:

one day

'at unspecified time' is the definition.
(one day in the future)

I don't understand how the rest of the clue works.

(Other definitions for one day that I've seen before include "sometime" , "In time to come" , "#Eventually" .)

I've seen this clue in The Guardian.
