How to Retrieve Client's Timezone Using AJAX with jQuery and PHP?

How to Retrieve Client's Timezone Using AJAX with jQuery and PHP

,Question:

How can I determine the timezone used by a client in a PHP application, ideally returning the time offset in seconds from UTC?

,Answer:

Below is a solution that employs jQuery and PHP:

PHP Code:

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

This code initializes the session and retrieves the client's timezone from the session variable 'time'.

jQuery Code:

<code class="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://domain.com/timezone.php",
      data: 'time='+ visitortimezone,
      success: function(){
        location.reload();
      }
    });
  }
});</code>
Copy after login

This jQuery code runs on the client side when the page loads. It detects whether the timezone has already been set and, if not, sends the current client timezone to a PHP script named 'timezone.php'.

timezone.php Script:

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

This PHP script simply stores the client's timezone in the session variable 'time'.

Usage:

  1. Include jQuery in the header section of the PHP page:
<code class="html"><script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script></code>
Copy after login
  1. Paste the jQuery code into the page.
  2. Create a PHP file named 'timezone.php' and upload it to the same directory as the PHP page.
  3. Make sure to update the URL in the jQuery code to point to the actual domain where 'timezone.php' is located.

Once this setup is complete, the PHP code will be able to access the client's timezone through the session variable 'time'. The timezone will be represented as a UTC/GMT time zone offset in seconds, such as -7 for GMT-7.
