javascript - 将 Moment utc 时间转换为 unix 时间

Question

大家好，我想知道如何使用库 moment.js 将日期转换为 Unix 时间戳，以便将 oldDate 与另一个日期进行比较。

这是我尝试过的:

var oldDate = (moment.unix(1490632174)).format();
// here I got the Date in string format
var newDate= moment.utc('2017-03-27T18:29:59+02:00', "YYYY-MM-DD");
// now I want to convert it again into unix timestamp and I don't know how to do it.
console.log(oldDate, newDate);

文档是一件很棒的事情。 Unix Timestamp (seconds)

moment().unix();

moment#unix outputs a Unix timestamp (the number of seconds since the Unix Epoch).

moment(1318874398806).unix(); // 1318874398

This value is floored to the nearest second, and does not include a milliseconds component.

var oldDate = moment.unix(1490632174).unix();
// here I got the Date in string format
var newDate= moment.utc('2017-03-27T18:29:59+02:00', "YYYY-MM-DD");
// now I want to convert it again into unix timestamp and I don't know how to do it.
console.log(oldDate, newDate.unix());
