Rotation of gameObject

Hi guys. I use this simple code

using UnityEngine;
using System.Collections;

public class RuotaCam : MonoBehaviour {
	public Transform da, to;
	public float speed = 0.1F;

	void Start () 
	void Update () {
        transform.rotation = Quaternion.Lerp(da.rotation, to.rotation, Time.time * speed);

With this script my object turns clockwise… if I want that it turns anticlockwise? How can I do?

(I’m sorry for my english)

This may be able to help. I had a similar issue to yours and found a pretty decent solution. The other answer there might also be of use.
