Determine a user's timezone

Question

Is there a standard way for a web server to be able to determine a user\'s timezone within a web page?

Perhaps from an HTTP header or part of the user-agent

Answer 1

Here is a robust JavaScript solution to determine the time zone the browser is in.

>>> var timezone = jstz.determine();
>>> timezone.name(); 
"Europe/London"
