我正在使用 react/redux 开发一个应用程序，并且我开始使用库react-intl来格式化消息和日期。
我已经能够在<FormattedDate>标签中显示它使用的时区。
我想选择所有可能存在的时区，因此当用户选择一个时区时，<FormattedDate>会自动更改为该格式。
我没有找到如何使用 react-intl 列出所有可能的时区。
我也在谷歌搜索过，我没有找到任何内置的 javascript 函数。
是这样吗？我如何获得该列表？
注意：不要认为它是同一个问题，因为我不想使用外部库，如果可能的话，如果它是唯一的解决方案，那么我将不得不以这种方式处理...：/
我最近创建了一个包含所有时区的数组，发现Chromium 71.0.3578.98 中缺少几个官方时区。
您可以在我报告的错误的评论中看到该数组。为方便起见，我在下面包含了数组：

let date = new Date;
aryIannaTimeZones.forEach((timeZone) => {
let strTime = date.toLocaleString("en-US", {
timeZone: `${timeZone}`
});
console.log(timeZone, strTime);
});如果你和我一样，想知道为什么有这么多时区，看看这个问题。
对于未来的搜索者，可以使用moment-timezone获取所有时区的列表。
import momentTZ from 'moment-timezone';
const defaultTimeZone = momentTZ.tz.guess();
const timeZonesList = momentTZ.tz.names();
我也需要一个完整的时区列表，其中包含预先格式化的数据，例如：
{
name: "America/Los_Angeles",
alternativeName: "Pacific Time",
group: ["America/Los_Angeles"],
countryName: "United States",
mainCities: ["Los Angeles", "San Diego"],
rawOffsetInMinutes: -480, // "raw" time zone offset, when there's no DST in place
rawFormat: "-08:00 Pacific Time - Los Angeles, San Diego",
currentTimeOffsetInMinutes: -420, // "current" time zone offset, this is why getTimeZones() is a method and not just an object: it can only work at runtime
currentTimeFormat: "-07:00 Pacific Time - Los Angeles, San Diego",
}
由于我找不到一个好的列表也可以维护，我为它创建了一个 npm 包：https : //github.com/vvo/tzdb/。时区列表会在发生更改时自动更新（例如新时区）。
如果您需要使用时区操作日期，则可以使用https://github.com/moment/luxon。
时区列表被分组以减少时区的数量。我们仅在以下情况下进行分组：相同的国家/地区和相同的偏移量（DST，非 DST）。
这基本上为您提供了一个与 Google 日历非常接近的时区列表。
祝你好运！
我没有通过浏览器 javascript 找到时区列表，所以创建了时区列表数组并使用了它。
直到 2020 年 12 月 25 日在 JAVA 11 ZoneRulesProvider.java
创建数组/集合并在没有外部库的情况下使用它
我找到了 600 个排序的时区

react-intl 库的时区功能完全由集成到浏览器中的ECMAScript 国际化 API功能提供。
虽然 IANA 时区支持是该规范的一部分，但目前仅涵盖两种情况：
将Date对象格式化为字符串，在此过程中转换为特定时区。
确定用户的本地时区标识符。
不幸的是，规范没有定义用于枚举可用时区列表的函数。
此外，请注意，目前对它所具有的两个功能的支持仅限于少数浏览器。可能需要很长时间才能依赖这些功能。的ECMAScript的兼容性表显示了支持哪些浏览器。在DateTimeFormat你会发现“resolvedOptions（）的timeZone默认为主机环境”和“接受IANA时区名”跟踪这些功能。
