How To Get The Current Time/timezone Of The User Visiting My Website?

I am working on an application which utilizes PHP (Zend Framework) and JavaScript (jQuery). I'm trying to get the current time of the user visiting the site. Is this possible? How

Solution 1:

adapted from: http://kennyshu.blogspot.com/2009/05/javascript-get-clients-timezone.html

<scripttype="text/javascript">var gmtOffset
  functiontimezone()  
  {  
    var localTime = newDate();  
    //this one will give you the GMT offset  
    gmtOffset = localTime.getTimezoneOffset()/60 * (-1);  
  }  
  </script>

then post back the variable gmtOffset to your application.

Solution 2:

You can get their ip and look it up via a web service or a database, of which I'm sure someone will reply with, or has already replied with in the duplicate question. :-)
