What is the limitation period for filing a federal habeas petition?

The judgment therefore became final on August 18, 2009, and the one-year limitations period commenced running the following day, August 19, 2009. See Patterson v. Stewart, 251 F.3d 1243, 1246 (9th Cir. 2001). Thus, petitioner had until August 18, 2010, to file his federal habeas petition. However, he did not file the instant petition until February 5, 2012. Dckt. No. 1 at 7. Absent tolling, his application in this court is more than a year late.
