A lo-o-ong time (4)

Ross

I believe the answer is:

eons

'a lo-o-ong time' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for eons that I've seen before include "Years and years" , "Divisions of archaeological time" , "Divisions of geological time" , "Very long periods (US)" , "Nose (anag)" .)

I've seen this clue in The New York Times.
