How to implement a cookie with timestamp on GTM

Insert the following script to Google Tag Manager:

var createCookie = function(cookieName, value) {
    document.cookie = cookieName + "=" + encodeURI(value) + ";domain=chemistwarehouse.com.au;path=/;secure;samesite=strict";
  }
  
createCookie("meiro_product_added_timestamp", new Date().toISOString());

The first part of the script states a function that can be called whenever there is a need to create a cookie. You will need to input a cookie name and its value.
