为什么Moment.JS无法正确解析24小时日期

Question

Whenever I parse dates using moment.js & node, it is exactly 12 hours out from what it should be. Consider the following test:

var moment = require('moment');

var dt1 = moment('14:00, 10 Jun 2014', 'HH:mm, DD MMM YYYY').toDate();
console.log('dt1:' + JSON.stringify(dt1, null, 4));

var dt2 = moment('02:00, 10 Jun 2014', 'HH:mm, DD MMM YYYY').toDate();
console.log('dt2:' + JSON.stringify(dt2, null, 4));

It gives the output:

dt1:"2014-06-10T02:00:00.000Z"
dt2:"2014-06-09T14:00:00.000Z"

Its almost like its parsing it using some crazy timezone and not just parsing the date in my local timezone as I want, which I would have thought would be be the default behaviour.

How can I make it work properly?

Answer 1

尝试以下内容

var dt1 = moment('14:00, 10 Jun 2014', 'HH:mm, DD MMM YYYY').format('HH:mm, DD MMM YYYY');

Answer 2

Moment.js is working correctly. Source of your problem is JSON.stringify that converts date to UTC. So you need to add your timezone to timestamp to fix that. And simplest way to do that is to warp your first moment object to second one for changing of format and set default format using format call without parameters (look for Default format here).

moment(moment('02:00, 10 Jun 2014', 'HH:mm, DD MMM YYYY').toDate()).format();

Update:

It's more simple as @MattJohnson figure out. Not sure why it's not worked before for me, but it's just need to be:

moment('02:00, 10 Jun 2014', 'HH:mm, DD MMM YYYY').format()
