Two years after making CA generally which essentially means three years. But in August they are going to a general 18 hour long call reserve (with no trips before 10AM on your first reserve day in a group) in an effort to get more commuters to bid for narrow body CA. Plus serious ADD PAY for anyone willing to volunteer for short call. And you can aggressively pick up trips from open time to have at least some control of your own destiny while on reserve.
