Using TIME to animate alpha map and speed control.

I am trying to rotate through a texture and use it for the alpha values for a water fountain water fall. Problem is I am having trouble controlling the animation of the uv cordinates using TIME. Here is what I have already for the fragment.

void fragment() {

	float speed;
	vec2 uvo;
	uvo.x=(TIME*100.0*xspeed)/100.0;
	uvo.y=(TIME*100.0*yspeed)/100.0;



	float wateralpha=texture(noisealpha,UV+uvo).a;

	ALBEDO=watercol;
	//float wateralpha=1.0;
	ALPHA=wateralpha*alphaadjust;

}
