How to Efficiently Determine a User's Time Zone in PHP and JavaScript?

How to Determine a User's Time Zone

Problem:

How do you efficiently determine a user's time zone in both PHP and JavaScript?

Solution:

In PHP, you can retrieve the time zone offset as a session variable:

<code class="php"><?php
session_start();
$timezone = $_SESSION['time'];
?></code>
Copy after login

To do this via JavaScript, include jQuery and incorporate the following code in the section:

<code class="javascript"><script type="text/javascript">
$(document).ready(function() {
    if ("<?php echo $timezone; ?>".length == 0){
        var visitortime = new Date();
        var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
        $.ajax({
            type: "GET",
            url: "http://example.com/timezone.php",
            data: 'time='+ visitortimezone,
            success: function(){
                location.reload();
            }
        });
    }
});
</script></code>
Copy after login

Finally, create a timezone.php file with:

<code class="php"><?php
session_start();
$_SESSION['time'] = $_GET['time'];
?></code>
Copy after login

This combination of PHP and JavaScript will retrieve the user's time zone and store it as the $timezone variable in PHP.
