方法2：

// 时间戳转换为日期

            function timestampToTime(timestamp) {

                var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000

                Y = date.getFullYear() + '-';

                M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '-';

                D = (date.getDate() < 10 ? '0' + (date.getDate()) : date.getDate()) + ' ';

                s = (date.getSeconds() < 10 ? '0' + (date.getSeconds()) : date.getSeconds());

                return Y + M + D + h + m + s;

            }
//日期转换为时间戳
