总结一下Matt Johnson在代码方面的答案：
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script><script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jstimezonedetect/1.0.4/jstz.min.js"></script><script type="text/javascript"> $(document).ready(function(){ var tz = jstz.determine(); // Determines the time zone of the browser client var timezone = tz.name(); //For e.g.:"Asia/Kolkata" for the Indian Time. $.post("url-to-function-that-handles-time-zone", {tz: timezone}, function(data) { //Preocess the timezone in the controller function and get //the confirmation value here. On success, refresh the page. }); });</script>
