Check out timezone_abbreviations_list
http://us3.php.net/manual/en/function.timezone-abbreviations-list.php
It basically prints an array that contains each time zone and the offset
for that time zone. Maybe you can use that to get what you need.

only timezoneoffset. Is anyrelation between timezone offset and name?
Is ie available as table? Can anyne help me to d this or by suggest

Some time ago I asked a similar question and someone on this list was so
nice to provide me with the ECMAScript for the client side to pull out
the time zone bias.
The general code is this one
if(!isset($_COOKIE['GMT_bias'])) {
?>
<script type="text/javascript">
var Cookies = {};
/***
* @name = string, name of cookie
* @value = string, value of cookie
* @days = int, number of days before cookie expires
***/
Cookies.create = function (name, value, days) {
if (days) {
var date = new Date();
date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var expires = "; expires=" + date.toGMTString();
} else {
var expires = "";
}
document.cookie = name + "=" + value + expires + "; path=/";
this[name] = value;
}
var now = new Date();
Cookies.create("GMT_bias",now.getTimezoneOffset(),7);
window.location = "<?php echo $_SERVER['PHP_SELF'];?>";
</script>
<?php
} else {
echo $_COOKIE['GMT_bias'];
}
It will simply echo the bias in minutes, which should be good enough to
find out the client's time zone by name assuming you have some table for
lookups or can pull that from the server system (no idea how that works,
but other programming languages can do that. Since PHP can do anything
including cooking breakfast, there should be some way).
At least it gets you started.
