Converting Date and Time from a specific Time Zone to another using PHP Tutorial

In this tutorial, you can learn how to Convert Date and Time from a specific Time Zone to another using PHP Language. The tutorial aims to provide students and beginners with a reference for learning to set and manage date time zones using PHP Language built-in class or object. Here, I will be providing a simple web page script that demonstrates the conversion of a date and time from a specific time zone into a different time zone.

What is Time Zone?

A Time Zone offsets from Universal Time Coordinate (UTC). A time zone is a region that adheres to a common standard time for social, commercial, and legal activities. Because it is easy for locations in frequent communication to preserve the same time, time zones typically follow the boundaries between countries and their subdivisions rather than rigidly following longitude.

How to convert Date and Time Zone from a specific Time Zone to another?

The Date and Time time zone can be easily converted from a specific time zone to another time zone using the PHP's built-in classes or objects called DateTime and DateTimeZone. These 2 PHP classes can be used to set the specific date and time into a certain Time Zone and generate the different time zone offset values.


The below PHP snippet demonstrates the usage of the DateTime and DateTimeZone classes of PHP to convert the date time zones.

  1. <?php
  2. // March 25, 2023 12:45 AM
  3. $dateTime = "2023-03-25 00:45";
  4. // Set Date TimeZone as UTC
  5. $dateTime = new DateTime($dateTime, new DateTimeZone('UTC'));
  6. // Convert Date Time to 'Asia/Manila' Time Zone
  7. $dateTime->setTimezone(new DateTimeZone('Asia/Manila'));
  8. // Converted Value
  9. $convertedValue = $dateTime->format("F d, Y g:i A");
  10. // output: March 25, 2023 08:45 AM
  11. ?>

Example Web Page

The below scripts result in a simple web page written in HTML, CSS, and PHP. The contains a simple page layout with date and time form to convert the time zone from UTC to 'Asia/Manila'. The Formatted UTC and converted (Asia/Manila) date and time values are both shown in a single panel.

Page Interface

The following script is a PHP file script named index.php. It contains the HTML elements of the page layout, panels/containers, and form elements of the web page. This file also contains the PHP script for converting the entered date and time from UTC to Asia/Manila Time zone.

The scipt below is the CSS file script known as style.css. It contains the custom style or codes for some of the page elements.

  1. @import url('" rel="stylesheet');

  15. body,
  16. html{
  17. height: 100%;
