Add a bool for when the game ends to stop the timeLeft from going down and pin the value.

using UnityEngine;
using System.Collections;

public class Click : MonoBehaviour
{
	float timeLeft = 60.0f;
	public UnityEngine.UI.Text Time;
    private bool isGameStarted = false;

	public UnityEngine.UI.Text goldDisplay;
	public int gold = 0;
	public int goldperclick = 1;

	private bool gameEnded = false;

	void Update()
	{
		goldDisplay.text = "Score: " + gold;

		if (timeLeft > 0 && gameEnded == false)
		{
			timeLeft -= UnityEngine.Time.deltaTime;
			Time.text = "" + Mathf.Round(timeLeft);

			if (timeLeft < 0)
			{
				timeLeft = 0;
                            isGameStarted = false;
				gameEnded = true; // prevent from calling all the text updates after time is less than 0 and pin it at 0
			}
		}

		if (gameEnded == true)
		{
			// do something, popup a game ended canvas, load a level, whatever.
		}
	}

	public void Clicked()
	{
            if (isGameStarted)
            {
		    gold += goldperclick;
            }
            else
            {
                isGameStarted = true; // isGameStarted is false on the first click
                // if you want to get gold on the first click uncomment out below
                gold += goldperclick;
            }
	}
}
