一个简单的时间格式化工具类，传入时间戳就OK，

timeConvertUtil = (timestamp) => {
        let date = new Date(timestamp);
        let Y = date.getFullYear() + '-';
        let M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';
        let D = date.getDate() + ' ';
        let h = date.getHours() + ':';
        let m = date.getMinutes() + ':';
        let s = date.getSeconds();
        return Y + M + D + h + m + s;
    }
