日期和时间戳的相互转化

var startStamp = "2018-08-27 21:20:44";  

var startStamp = Number(new Date()); //1557398861913  ----->日期转化为时间戳

 

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

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

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

        var D = date.getDate() + ' ';

        var h = date.getHours() + ':';

        var m = date.getMinutes() + ':';

        var s = date.getSeconds();

        return Y+M+D+h+m+s;

    }

    timestampToTime(1403058804);

    console.log(timestampToTime(1403058804));//2014-06-18 10:33:24
