javascript - finding the time zone from which a browsers connection to a Web server -

I'm not in the web (client / server) application development, but for some time this question was -

If some web browsers (IE / Firefox) make a connection to some websites, then it is possible that the web server can detect the time zone of the client, or find the current local time of the customer location, and the page But could be able to display it.

If so, how is the time zone detected? Can the client perform a role in this process or alone without the client without any input to the client?

Use something like:

< Pre> & lt; Script type = "text / javascript" language = "javascript" & gt; Var tz = (new date) .getTimezoneOffset () / - 60; & Lt; / Script & gt;
