What is the test for a motion to alter or amend judgment under Rule 59(e)?

motion to alter or amend judgment under Federal Rule of Civil Procedure Rule 59(e) if it is filed within ten days of entry of judgment. See United States v. Nutri-Cology, Inc., 982 F.2d 394, 397 (9th Cir. 1992). Otherwise, it is treated as a Rule 60(b) motion for relief from a judgment or order. The motion here was filed well past ten days after the judgment, so it is properly construed as a Rule 60(b) motion.
