解析没有时区的日期javascript [英] Parse date without timezone javascript

问题描述

我想在 JavaScript 中解析没有时区的日期.我试过了:

I want to parse date without timezone in JavaScript. I have tried:

new Date(Date.parse("2005-07-08T00:00:00+0000"));

返回 2005 年 7 月 8 日星期五 02:00:00 GMT+0200(中欧夏令时)

Returns Fri Jul 08 2005 02:00:00 GMT+0200 (Central European Daylight Time)

new Date(Date.parse("2005-07-08 00:00:00 GMT+0000"));

返回相同的结果

new Date(Date.parse("2005-07-08 00:00:00 GMT-0000"));

返回相同的结果

我想解析时间:

1. 没有时区.

1. Without time zone.

不调用构造函数 Date.UTC 或 new Date(year, month, day).

Without calling constructor Date.UTC or new Date(year, month, day).

只是简单地将字符串传递给 Date 构造函数(没有原型方法).

Just simple passing string into Date constructor (without prototype approaches).

我必须生成 Date 对象，而不是 String.

I have to product Date object, not String.

推荐答案

日期被正确解析，只是 toString 将其转换为您的本地时区:

The date is parsed correctly, it's just toString that converts it to your local timezone:

let s = "2005-07-08T11:22:33+0000";
let d = new Date(Date.parse(s));

// this logs for me 
// "Fri Jul 08 2005 13:22:33 GMT+0200 (Central European Summer Time)" 
// and something else for you

console.log(d.toString()) 

// this logs
// Fri, 08 Jul 2005 11:22:33 GMT
// for everyone

console.log(d.toUTCString())

Javascript Date 对象是时间戳——它们只包含自纪元以来的毫秒数.Date 对象中没有时区信息.这个时间戳代表哪个日历日期(日、分、秒)是一个解释问题(to...String 方法之一).

Javascript Date object are timestamps - they merely contain a number of milliseconds since the epoch. There is no timezone info in a Date object. Which calendar date (day, minutes, seconds) this timestamp represents is a matter of the interpretation (one of to...String methods).

上面的例子表明日期被正确解析 - 也就是说，它实际上包含对应于格林威治标准时间2005-07-08T11:22:33"的毫秒数.

The above example shows that the date is being parsed correctly - that is, it actually contains an amount of milliseconds corresponding to "2005-07-08T11:22:33" in GMT.
