            radius = Math.max(width, height);
        }
        
        
        public function setTime(ratio:Number):void {
            foregroundMask.graphics.clear();

            foregroundMask.graphics.moveTo(0, -radius);
            
            if(ratio > 1 / 4) foregroundMask.graphics.lineTo(radius, 0);
            if(ratio > 1 / 2) foregroundMask.graphics.lineTo(0, radius);
            if(ratio > 3 / 4) foregroundMask.graphics.lineTo(-radius, 0);
            
            foregroundMask.graphics.lineTo(radius * Math.sin(Math.PI * 2 * ratio), -radius * Math.cos(Math.PI * 2 * ratio));
            
            foregroundMask.graphics.lineTo(0, 0);
            foregroundMask.graphics.lineTo(0, -radius);
