You may try to detect the timezone using javascript and here's a more robust version. Then include it in a hidden field or query string variable so that the server can fetch it.

You can use getTimezoneOffset() method in javascript.
It returns the time difference between Greenwich Mean Time (GMT) and local time, in minutes.
