How to Fix MySQL Error – Unknown or incorrect time zone: ‘zone_name’

MySQL is a popular open-source relational database management system used by many websites and applications. It provides a robust and efficient way to store and retrieve data. However, like any software, MySQL can encounter errors that can disrupt its normal operation. One such error is the “Unknown or incorrect time zone: ‘zone_name'” error.

Understanding the Error

The “Unknown or incorrect time zone: ‘zone_name'” error occurs when MySQL is unable to recognize or find the specified time zone. This error can occur for various reasons, such as:

  • The time zone specified in the query or configuration file does not exist in the MySQL time zone database.
  • The time zone tables in the MySQL database are corrupted or missing.
  • The MySQL server does not have the necessary privileges to access the time zone tables.

Fixing the Error

To fix the “Unknown or incorrect time zone: ‘zone_name'” error, you can follow these steps:

Step 1: Check the Time Zone

First, verify that the time zone you are using is valid and exists in the MySQL time zone database. You can do this by executing the following query:

SELECT * FROM mysql.time_zone WHERE Name = 'zone_name';

If the query returns no results, it means that the specified time zone does not exist in the database. In this case, you need to choose a valid time zone or update the time zone data in MySQL.

Step 2: Update Time Zone Data

If the specified time zone does not exist in the MySQL time zone database, you can update the time zone data by following these steps:

  1. Download the latest time zone data from the IANA (Internet Assigned Numbers Authority) website. You can find the data at https://www.iana.org/time-zones.
  2. Extract the downloaded file and locate the “timezone_*.sql” file that matches your MySQL version.
  3. Import the time zone data into MySQL by executing the following command:
mysql -u root -p mysql < /path/to/timezone_*.sql

Replace “/path/to/timezone_*.sql” with the actual path to the “timezone_*.sql” file on your system.

Step 3: Grant Privileges

If the MySQL server does not have the necessary privileges to access the time zone tables, you can grant the required privileges by executing the following commands:

GRANT SELECT ON mysql.time_zone TO 'mysql_user'@'localhost';
FLUSH PRIVILEGES;

Replace “mysql_user” with the actual MySQL user that needs the privileges.

Conclusion

The “Unknown or incorrect time zone: ‘zone_name'” error in MySQL can be resolved by ensuring that the specified time zone exists in the MySQL time zone database, updating the time zone data if necessary, and granting the appropriate privileges to the MySQL server. By following these steps, you can fix this error and ensure the smooth operation of your MySQL database.
