时间戳显示格式为几天前、几分钟前、几秒前---vue过滤器

//时间显示问题（几天前、几分钟前）Vue.filter('fomatTime', function (valueTime) {  if(valueTime){    var newData =  Date.parse(new Date());    var diffTime = Math.abs(newData-valueTime);    if (diffTime > 7 * 24 * 3600 * 1000) {      var date = new Date(valueTime);      var y = date.getFullYear();      var m = date.getMonth() + 1;      m = m < 10 ?
