Im trying to make a table with vue.js and one of the row is supposed to print a date i receive in epoch time. but fail to convert it in a readable date and just get "invalide date" printed on my browser.
Here is how i convert it
  var sec = 1588351494;
    var tmp =new Date(0);
    tmp.setUTCDate(sec);
    var res= tmp;
her is how it's made to be able to be called as a vue.js object
      return {
        tableData: [
          {
            uid: '01020304050607',
            lastReadDate: res,
          },
        ]
      }
And then i simply print it in my html page doing this, which print the "invalide date" in the row.
          <td>
            {{row.lastReadDate }}
          </td>
