How to Set the Time Zone of MySQL: A Complete Guide

🕑 Ever wondered how to set the time zone of MySQL? ⏰ Don't worry, you're not alone! Many users struggle with this common issue. In this guide, we'll walk you through the steps to solve this problem and ensure your MySQL database reflects the correct time zone.

The Problem

🤔 Have you noticed that the time returned by the now() function in MySQL differs on different servers? 😱 This can be quite confusing and may lead to incorrect data analysis if not addressed properly. The issue lies in the time zone configuration of your MySQL server.

The Solution

✅ Follow these simple steps to set the time zone of your MySQL database:

1. Check the Current Time Zone: First, you need to identify the current time zone setting of your MySQL server. To do this, run the following query in your MySQL console:

mysql> SELECT @@global.time_zone;

1. Set the Time Zone: Once you know the current time zone, you can proceed to set the desired time zone for your MySQL server. There are two ways to achieve this:

   • Set Time Zone Temporarily: If you only want to set the time zone temporarily (until the server restarts), use the following query:

   mysql> SET time_zone = '<timezone>';

   Replace <timezone> with the desired time zone. For example, to set the time zone to 'US/ Pacific', you would run:

   mysql> SET time_zone = 'US/Pacific';

   • Set Time Zone Permanently: If you want to set the time zone permanently (even after server restarts), you need to modify the MySQL configuration file. Open the MySQL configuration file in your favorite text editor (e.g., /etc/mysql/my.cnf or /etc/my.cnf), and look for the [mysqld] section. Add or modify the following line:

   [mysqld] default_time_zone = '<timezone>'

   Replace <timezone> with the desired time zone (e.g., 'US/Pacific').

2. Restart MySQL Server: After making changes to the MySQL configuration file, you need to restart the MySQL server for the changes to take effect. Run the following command in your terminal:

$ sudo service mysql restart

1. Verify Time Zone: Finally, to confirm that the time zone has been set correctly, run the following query in your MySQL console:

mysql> SELECT @@global.time_zone;

The query should now return the newly set time zone.

🎉 Congratulations! You have successfully set the time zone of your MySQL database! Now all your queries involving time will reflect the correct time zone.
