Get client's timezone offset in ExpressJS

If you control the client, you can do this with client-side JavaScript.

If you don't (e.g. you're building a server-side component like an API), then you can't pull it out of the HTTP request (unless you're using sessions, but even that's not necessarily reliable).

On the upside, if it's only server-side, you shouldn't worry about it either: set all your date objects as UTC or a Unix timestamp and leave it to the client developer to handle timezones.

        var mySplitResult = strLocalZone.split(" ");

        var newLocalZone = mySplitResult[5].slice(0,mySplitResult[5].length-2) +':'+mySplitResult[5].slice(mySplitResult[5].length-2,mySplitResult[5].length);
        document.getElementById("hdnTimeZone").value = newLocalZone;

How to get client's timezone?

Check out this article on how to detect the timezone by setting a Cookie through JavaScript that will hold the client's timezone. It's rather lenghty, but that is because it is quite verbose. I've implemented a solution along these lines in one of my own apps and it works quite well.

You could also send the timezone via Ajax to the server and have it do whatever you need to do it with then. Or, if you are not doing any serverside calculations with it, just apply the timezone client side where needed. Really depends on your usecase.

In addition to that, I suggest you let the visitor set his timezone himself and store that in the Cookie or a Session.

How to detect the timezone of a client?

Unfortunately this information is not passed in HTTP headers.

Usually you need cooperating JavaScript to fetch it for you.

Web is full of examples, here is one http://www.coderanch.com/t/486127/JSP/java/Query-timezone
