I got moment-timezoneand the data file, but I can't figure out how to use it to determine the client's local time zone and display something like:
我得到moment-timezone了数据文件，但我不知道如何使用它来确定客户端的本地时区并显示如下内容：

As of moment-timezone 0.1.0, you can use the formatting additionsto get the abbreviation of a specifictime zone:
从 moment-timezone 0.1.0 开始，您可以使用格式添加来获取特定时区的缩写：
moment().tz("America/Los_Angeles").format('z'); // PST or PDT
As of version 0.5.0, you can now guess the user's localtime zone, which when combined with the above technique, allows you to do the following:
从 0.5.0 版本开始，您现在可以猜测用户的本地时区，结合上述技术，您可以执行以下操作：
moment().tz(moment.tz.guess()).format('z');
Assuming the guess was correct, it will display the associated abbreviation.
假设猜测是正确的，它将显示相关的缩写。

Probably this is not a good way, but I did not want to add any additional scripts in my project for local time zone, so I investigated a moment object and I get the local time zone by the code I wrote below:
可能这不是一个好方法，但我不想在我的项目中为本地时区添加任何额外的脚本，所以我调查了一个时刻对象，并通过我在下面编写的代码获得了本地时区：
var test = momentUpdateDate._d.toString().substring(test.indexOf('(')+1, test.indexOf(')'));

Some time in the past 5 years, this stopped working. Now try:
在过去 5 年的某个时候，这停止了工作。现在尝试：
var timeZone = moment.tz.guess();
var time = new Date();
var timeZoneOffset = time.getTimezoneOffset();
moment.tz.zone(timeZone).abbr(timeZoneOffset);

From the latest moment timezone docs
从最新时刻时区文档
moment.tz(String).format("Z z"); // -08:00 PST
moment.tz(String).zoneAbbr(); // PST
moment.tz(String).zoneName(); // PST
Some examples:
一些例子：
moment.tz(moment.tz.guess()).zoneAbbr(); // PST
moment.tz("America/New_York").zoneAbbr(); // EST
