Javascript：如何从UTC字符串和偏移量解析日期？ [英] Javascript: How to parse date from UTC string and offset?

问题描述

情景

我有一个字符串格式的UTC日期和一个以分钟为单位的关联偏移号：

I have a UTC date in string format and an associated offset number in minutes:

• 日期：2017-10-01T12：00：00.000Z


• 抵消：360

用户的浏览器位于Mountain Standard Time（-7）时区。日期值是从中央标准时间（-6）时区记录的，并与其偏移量一起保存（因此偏移量为360分钟）。可以假设偏移量不包括夏令时。

The user's browser is in the Mountain Standard Time (-7) timezone. The date value was recorded from the Central Standard Time (-6) timezone, and was saved along with its offset (hence the offset of 360 minutes). It can be assumed the offset does not include for daylight savings time.

问题

如何使用记录时区的偏移量解析UTC日期？换句话说，尽管用户的浏览器是MST，我仍然希望将字符串中的日期显示为2017-10-01 6:00 AM。不需要显示时区。这是否可以使用时区时区而不具有时区名称并且只有不包含DST的偏移量？

How do I parse the UTC date using the offset for the timezone it was recorded in? In other words, despite the user's browser being MST, I still want to display the date in a string as something like "2017-10-01 6:00 AM". Displaying the timezone is not required. Is this possible using moment-timezone without having the name of the timezone and just having the offset that doesn't include DST?

推荐答案

那就是你需要的吗？

const moment = require('moment');
moment
  .utc('2013-06-20T07:00:00.427')
  .zone(-360)
  .format();

在这里你可以找到很多显示选项 - > http://momentjs.com/docs/#/displaying/

here you'll find a lot of displaying options -> http://momentjs.com/docs/#/displaying/

或者只是：

const date = new Date('2017-10-01T12:00:00.000Z');
date.setMinutes(-360);
date.toISOString();
