This page shows your timezone data; this data is derived from window.Date JavaScript API. There are six methods designed to extract timezone data from the javascript engine. The last two methods are "aggressive", meaning that, they can extract the real timezone even if you have a plugin to spoof your timezone data. The first four methods may conceive fake timezone but the last two will not and always return the actual time.

To work with this web app, simply click a method from the above drop-down list. The app will render the timezone data in the above table after a while. Please note that beside window.Date API, this page uses window.Intl.DateTimeFormat JavaScript API as well. Moreover, the page shows you the internet beat value, time string on the server and milliseconds since January 1970.

In the drop-down list above, the first two methods are "normal". In other words, they use common approaches to compute the timezone. If you have a spoofer plugin, the first two methods will fail to extract the real data. Methods 3 and 4 are marked as moderate which means they may extract the real data even if you have a spoof mechanism. But this is not guaranteed and they may fail to render the real info. The last two methods are marked as aggressive; meaning that most probably these methods catch the real timezone even if you have a spoof mechanism (plug-in or addon). Please note that in some situations these methods may also fail to render the actual time due to bugs or spoofer plugins that can bypass the underlying logic.
