Setup PHP Timezone in Apache on Ubuntu 24.04

Set up Ubuntu timezone

Setting your Ubuntu timezone correctly is the first step to making sure your server’s time is accurate for all programs, including PHP. You can easily check your server’s current timezone by running the ‘timedatectl’ command in your terminal. This ensures your server operates on the right time.

To find out which timezone your server’s is in or configured for, run the command below.

timedatectl

The command above should output a result similar to the one below.

               Local time: Tue 2025-02-18 14:51:49 CST
           Universal time: Tue 2025-02-18 20:51:49 UTC
                 RTC time: Tue 2025-02-18 20:51:50
                Time zone: America/Chicago (CST, -0600)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

There’s nothing to do if the server is in the correct time zone.

If not, you can use the steps below to change the server’s timezone.

First, list all the time zones available to your server by running the command below.

sudo timedatectl list-timezones

The command will output a list of all the time zones.

Africa/Abidjan
Africa/Accra
Africa/Addis_Ababa
Africa/Algiers
Africa/Asmara
Africa/Asmera
Africa/Bamako
Africa/Bangui
.....

Once you find the timezone to use, run the command below to set it up on your server.

sudo timedatectl set-timezone America/Chicago

Replace the highlighted Continent or Country/City in the command to match yours.

Alternatively, you can run the command below to select your server’s time zone interactively.

sudo dpkg-reconfigure tzdata

Use the arrow up/down key to select the correct timezone.

The server’s time zone should be updated.

Set PHP timezone

After setting your Ubuntu server’s timezone, you can easily set your PHP timezone to match it for accurate web application times. Open the ‘php.ini’ file for your specific PHP version by running ‘sudo nano /etc/php/YOUR_PHP_VERSION/apache2/php.ini’. This allows you to update the timezone setting within PHP’s main configuration file.

To change or update the PHP timezone, run the command below to open each php.ini file at these locations.

Replace the highlighted version number (8.3) with the correct PHP version installed on the server.

sudo nano /etc/php/8.3/apache2/php.ini
sudo nano /etc/php/8.3/cli/php.ini

Update the [Date] section in the file.

[Date]
; Defines the default timezone used by the date functions
; https://php.net/date.timezone
date.timezone = America/Chicago

Save the file and exit.

sudo sed -i "s/;date.timezone.*/date.timezone = America/Chicago/" /etc/php/8.3/apache2/php.ini
sudo sed -i "s/;date.timezone.*/date.timezone = America/Chicago/" /etc/php/8.3/cli/php.ini

Restart PHP to apply the settings.

sudo systemctl restart apache2

Verify the Configuration

Verifying your PHP timezone configuration is simple by checking the ‘phpinfo()’ output. Create a file named ‘info.php’ with the code ‘<?php phpinfo(); ?>’ and access it in your web browser. This page shows all PHP settings, letting you confirm your timezone is correctly applied.

   <?php
   phpinfo();
   ?>

Access this file through your web browser (http://localhost/info.php) and look for the date.timezone setting to verify it is set correctly.

That should do it!

Conclusion:

Setting the correct timezone in PHP with Apache on Ubuntu is crucial for ensuring that your applications accurately handle time-sensitive data. By following the steps outlined, you can:

• Verify the server’s current timezone and update it if necessary.
• Make sure the PHP timezone aligns with the server’s timezone for consistency.
• Update the php.ini files or use command-line shortcuts for efficiency.
• 🔄 Restart the Apache server to apply the changes.
• Verify the changes by checking the date.timezone setting with a PHP info page.

Ensuring that your system timezone is set correctly is vital for the reliability and accuracy of your web applications.
