There is no fixed time frame and it varies from person to person based on your current skill set. From personal experience 6-10 weeks might 'be an ideal time.

The best way to go about, would be to start off with a couple of mock GRE's evaluate your scores,know you problem areas, work on them and keep evaluating yourself every 3-4weeks to figure out how much more time you would need. Though there is no point rushing remember that unless you give yourself a fixed deadline your efforts might not justify the cause.
