国际标准时间转为时间轴，时间戳转时间轴，时间轴转时间戳

 //将国际时间转为时间轴方法
      formatTen(num) { 
          return num > 9 ? (num + "") : ("0" + num); 
      }, 
      formatDate(date) { 
          let year = date.getFullYear(); 
          let month = date.getMonth() + 1; 
          let day = date.getDate(); 
          let hour = date.getHours(); 
          let minute = date.getMinutes(); 
          let second = date.getSeconds(); 
          return year + "-" + this.formatTen(month) + "-" + this.formatTen(day); 
      },

时间戳转时间轴

        getTime(nS){     
             return new Date(parseInt(nS) * 1000).toLocaleString().replace(/:\d{1,2}$/,' ');     
        }, 

时间轴转时间戳

      dateTime(index) {
        var strtime = index;
        var date = new Date(strtime);
        var time = Date.parse(date) / 1000;
        return time;
      }
