时间戳转换成时间

 1 //时间戳转换
 2    function timestampToTime(timestamp) {
 3       let 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
 4       let Y = date.getFullYear() + \'-\';
 5       let M = (date.getMonth()+1 < 10 ? \'0\'+(date.getMonth()+1) : date.getMonth()+1) + \'-\';
 6       let D = date.getDate() + \' \';
 7       var h = date.getHours() + \':\';
 8       var m = date.getMinutes() + \':\';
 9        var s = date.getSeconds();
10       return Y+M+D;
11     }
