Can't set expiry about vue-cookies

[cmp-cc]

Thank you very much for driving me

expiry testing is valid.

window.$cookies.set("TestNumber","5s Later,expiry",5);

var timer = setInterval(function(){
   if(VueCookies.isKey("TestNumber")){
     console.log(VueCookies.get("TestNumber"))
   } else {
    console.log("cookie name: TestNumber not find\t", VueCookies.get("TestNumber"))
    clearInterval(timer)
   }
},1 * 1000)

results

5s Later,expiry  
5s Later,expiry
5s Later,expiry
5s Later,expiry       
VM821:7 cookie name: TestNumber not find	 null

In line with expectations

---

this.$cookies.set('name', 'value', 1); // 1 second later, expiry

this.$cookies.set('name', 'value', 60); // 1 minute later, expiry

this.$cookies.set('name', 'value', new Date(2018, 1, 1)); // 2018 yeas, expiry

this.$cookies.set('name', 'value', "Mon, 01 Jan 2018 12:00:00 GMT"); // input a string
