Moment.js diff between UTC dates
提问by dzm
I'm using moments.jsfor working with dates in javascript. All dates are in UTC (or should be).
我正在使用moment.js在 javascript 中处理日期。所有日期都是UTC（或应该是）。
I have the following date (60 minutes from current time):
我有以下日期（距当前时间 60 分钟）：
//Wed, 04 Apr 2012 21:09:16 GMT
to = moment.utc().add('m', 60).toDate();
Now I want to get the difference in seconds between this date and the current UTC datetime, so I do:
现在我想得到这个日期和当前 UTC 日期时间之间的秒数差异，所以我这样做：
seconds = moment.utc().diff(to, 'seconds');
This returns 10800instead of 3600, so 3 hours, instead of one.
这将返回10800而不是3600，所以是 3 小时，而不是 1 小时。
Any ideas what I'm doing wrong?
任何想法我做错了什么？
Thank you!
谢谢！
EDIT:
编辑：
I updated the line to seconds = moment().diff(to, 'seconds');and it gets the currect seconds, but it's -3600instead of positive.
我更新了该行seconds = moment().diff(to, 'seconds');并获得了当前秒数，但它-3600不是正数。

I now have these two moment objects:
我现在有这两个矩对象：
{ _d: Thu, 05 Apr 2012 17:33:18 GMT, _isUTC: true }
{ _d: Thu, 05 Apr 2012 16:38:45 GMT, _isUTC: true }
d1 and d2.
d1 和 d2。
When I do d1.diff(d2, 'hours', true);this returns 4. It's definitely something to do with UTC I think, but it seems this shouldwork.
当我这样做时d1.diff(d2, 'hours', true);返回4. 我认为这绝对与 UTC 有关，但似乎这应该可行。

This is a legitimate bug. I just filed it here: https://github.com/timrwood/moment/issues/261
这是一个合法的错误。我刚刚在这里归档：https: //github.com/timrwood/moment/issues/261
To get around it, use the following instead.
要解决它，请改用以下内容。
var a = moment.utc().add('m', 60).toDate(),
b = moment().diff(to, 'seconds'); // use moment() instead of moment.utc()
Also, if you need to get the toStringof the date, you can use moment().toString()as it proxies to the wrapped Date().toString()
此外，如果您需要获取toString日期，您可以使用moment().toString()它作为包装好的代理Date().toString()

Might be time zones kicking in because you are using toDate(). Try to just work directly with moment (i.e. change it to to = moment.utc().add('m', 60);).
可能是时区启动，因为您正在使用toDate(). 尝试直接使用 moment（即，将其更改为to = moment.utc().add('m', 60);）。
