You'll have you get the user's timezone using JavaScript, then change the timezone in PHP using date_default_timezone_set().

First you get the time with java script:

<script type="text/javascript">	var gmtOffset = -new Date().getTimezoneOffset()/60;</script>

Then you need to pass that value to PHP using AJAX, then you can use the offset to set the user's timezone in PHP with the function Synook mentioned. There are some useful scripts in the comments of the php.net manual page of that function.

ok thanks a lot. i have to check ajax first now. i dont know ajax. is ajax script can be run from mobile browsers?

AJAX is not a language, but just a usage model for the JavaScript XMLHttpRequest object. If a mobile browser supports JavaScript properly, it probably implements the XMLHttpRequest object too.http://w3schools.com/ajax/
