如何检测用户时区 [英] how to detect users timezone

问题描述

我需要知道我的用户目前的时区是基于他们的Ip或http标头。

i need to know what time zone is currently my users is in based on their Ip or http header.

这对我来说非常紧急。我有很多关于这个问题的答案，但我不能理解这些答案。
有人说使用 -new Date（）。getTimezoneOffset（）/ 60; （从这里）。这是什么意思？

This is very urgent to me. I got many answer regarding this issue, but i could not understood those answer. Some said use -new Date().getTimezoneOffset()/60;(from here) .But what does it mean ?

我在我的（index.php）的根目录中有一个 date_default_timezone_set（Asia / Calcutta）; 页。所以为此我必须动态获得时区，并将其设置为亚洲/加尔各答。

I have a date_default_timezone_set("Asia/Calcutta"); in the root of my (index.php)page. so for this i have to get the timezone dynamically and set it in place of Asia/Calcutta.
