How to Retrieve a User's Timezone Using PHP and JavaScript?

Get User Timezone

This guide explores two effective methods for obtaining a user's timezone: PHP and JavaScript.

PHP Approach:

This PHP code accesses the timezone as a variable:

<?php
    session_start();
    $timezone = $_SESSION['time'];
?>

Copy after login

JavaScript Approach:

In the section, include jQuery:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

Copy after login

Then, include the following jQuery code:

<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>

Copy after login

Finally, create a "timezone.php" file with the following code:

<?php
    session_start();
    $_SESSION['time'] = $_GET['time'];
?>

Copy after login

This approach uses jQuery and PHP to set the session variable "time" with the user's timezone and retrieves the value in the main PHP script.
