Like he said you can't measure fermentation in time as you just don't know how long it will take. Temperature will play a large roll in fermentation. Go back to science class where there is heat, there is a chemical reaction.
However to give you a typical, 7-10 days in a primary then rack to secondary. I like clarity is all. You can bottle in 3-4 weeks if you get impatient. 7-10 days in primary. 7-10 days in secondary. Bottle it let it age 3 weeks or so and throw it in the fridge. If you have more time though by all means take your time! It only gets better with age!
