[Star Wars] Why did master Sifo-Dyas order a clone army at least 10 years before the Clone Wars even came close to starting?

Sifo-Dyas only foresaw that a war was coming, he didn't know anything else. A clone army takes years to grow, so he contacted the Kaminoans as soon as possible. By the time the project was up and running the Sith had killed him and taken his place, and they could afford to be patient, especially since they needed to create an enemy for the clones to fight.
