How do I set the time zone of MySQL?

To set it for the current session, do:

SET time_zone = timezonename;

This work for me for a location in India:

SET GLOBAL time_zone = "Asia/Calcutta";
SET time_zone = "+05:30";
SET @@session.time_zone = "+05:30";

This is a 10 years old question, but anyway here's what worked for me. I'm using MySQL 8.0 with Hibernate 5 and SpringBoot 4.

I've tried the above accepted answer but didn't work for me, what worked for me is this:

db.url=jdbc:mysql://localhost:3306/testdb?useSSL=false&serverTimezone=Europe/Warsaw

If this helps you don't forget to upvote it :D

Keep in mind, that 'Country/Zone' is not working sometimes... This issue is not OS, MySQL version and hardware dependent - I've met it since FreeBSD 4 and Slackware Linux in year 2003 till today. MySQL from version 3 till latest source trunk. It is ODD, but it DOES happens. For example:

root@Ubuntu# ls -la /usr/share/zoneinfo/US
total 8

drwxr-xr-x  2 root root 4096 Apr 10  2013 .
drwxr-xr-x 22 root root 4096 Apr 10  2013 ..
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Alaska -> ../SystemV/YST9YDT
lrwxrwxrwx  1 root root   21 Jul  8 22:33 Aleutian -> ../posix/America/Adak
lrwxrwxrwx  1 root root   15 Jul  8 22:33 Arizona -> ../SystemV/MST7
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Central -> ../SystemV/CST6CDT
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Eastern -> ../SystemV/EST5EDT
lrwxrwxrwx  1 root root   37 Jul  8 22:33 East-Indiana -> ../posix/America/Indiana/Indianapolis
lrwxrwxrwx  1 root root   19 Jul  8 22:33 Hawaii -> ../Pacific/Honolulu
lrwxrwxrwx  1 root root   24 Jul  8 22:33 Indiana-Starke -> ../posix/America/Knox_IN
lrwxrwxrwx  1 root root   24 Jul  8 22:33 Michigan -> ../posix/America/Detroit
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Mountain -> ../SystemV/MST7MDT
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Pacific -> ../SystemV/PST8PDT
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Pacific-New -> ../SystemV/PST8PDT
lrwxrwxrwx  1 root root   20 Jul  8 22:33 Samoa -> ../Pacific/Pago_Pago
root@Ubuntu#

And a statement like that is supposed to work:

SET time_zone='US/Eastern';

But you have this problem:

Error Code: 1298. Unknown or incorrect time zone: 'EUS/Eastern'

Take a look at the subfolder in your zone information directory, and see the ACTUAL filename for symlink, in this case it's EST5EDT. Then try this statement instead:

SET time_zone='EST5EDT';

And it's actually working as it is supposed to! :) Keep this trick in mind; I haven't seen it to be documented in MySQL manuals and official documentation. But reading the corresponding documentation is must-do thing: MySQL 5.5 timezone official documentation - and don't forget to load timezone data into your server just like that (run as root user!):

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

Trick number one - it must be done exactly under MySQL root user. It can fail or produce non-working result even from the user that has full access to a MySQL database - I saw the glitch myself.

You can specify the server's default timezone when you start it, see http://dev.mysql.com/doc/refman/5.1/en/server-options.html and specifically the --default-time-zone=timezone option. You can check the global and session time zones with

SELECT @@global.time_zone, @@session.time_zone;

set either or both with the SET statement, &c; see http://dev.mysql.com/doc/refman/5.1/en/time-zone-support.html for many more details.

If you're using PDO:

$offset="+10:00";
$db->exec("SET time_zone='".$offset."';");

If you're using MySQLi:

$db->MySQLi->query("SET time_zone='".$offset."';");

More about formatting the offset here: https://www.sitepoint.com/synchronize-php-mysql-timezone-configuration/

Edit the MySQL config file

sudo nano /etc/mysql/my.cnf

Scroll and add these to the bottom. Change to relevant time zone

[mysqld]
default-time-zone = "+00:00"

Restart the server

sudo service mysql restart

First to figure out what the time_zone is you can query

SHOW VARIABLES LIKE '%time_zone%'; 

Your output should be something similar as follows

**Variable_name**     **Value**
system_time_zone      CDT
time_zone             SYSTEM

Then if you want to confirm that you are in say some time zone like CDT instead of something like EST you can check what time it thinks your machine is in by saying

SELECT NOW();

If this is not the time you want you need to change it... all you need to do is SET time_zone = timezone_name. Make sure it is one that is in Continent/City format.

If you are on a shared server because you have a hosting service please refer to these answers regarding changing the php.ini file or the .htaccess file.

To set the standard time zone at MariaDB you have to go to the 50-server.cnf file.

sudo nano /etc/mysql/mariadb.conf.d/50-server.cnf

Then you can enter the following entry in the mysqld section.

default-time-zone='+01:00'

Example:

#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#

# this is read by the standalone daemon and embedded servers
[server]

# this is only for the mysqld standalone daemon
[mysqld]

#
# * Basic Settings
#
user            = mysql
pid-file        = /var/run/mysqld/mysqld.pid
socket          = /var/run/mysqld/mysqld.sock
port            = 3306
basedir         = /usr
datadir         = /var/lib/mysql
tmpdir          = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking

### Default timezone ###
default-time-zone='+01:00'

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.

The change must be made via the configuration file, otherwise the MariaDB server will reset the mysql tables after a restart!

if you use of named time-zone results in an error:

mysql> SET GLOBAL time_zone = "Asia/Bangkok";    
ERROR 1298 (HY000): Unknown or incorrect time zone: 'Asia/Bangkok'

you can try:

mysql_tzinfo_to_sql tz_file tz_name | mysql -u root -p mysql

and then:

SET GLOBAL time_zone = "Asia/Bangkok";
SET time_zone = "+07:00";
SET @@session.time_zone = "+07:00";

check what time is it:

SELECT NOW();

ref: https://dev.mysql.com/doc/refman/5.7/en/time-zone-support.html#time-zone-installation

From MySQL Workbench 8.0 under the server tab, if you go to Status and System variables you can set it from here.

Set MYSQL timezone on server by logging to mysql server there set timezone value as required. For IST

SET SESSION time_zone = '+5:30';

Then run SELECT NOW();

You can do this easily by changing the OS time zone if match your scenario.

In Ubuntu, to list time zones, run this command

sudo timedatectl list-timezones

To change the OS time zone, run this command with your timezone

timedatectl set-timezone America/New_York

Check The OS time zone, run

date

Then restart the MySQL

sudo service mysql restart

To Chek time zone in MySQL, login and run

SELECT TIMEDIFF(NOW(), UTC_TIMESTAMP);

On Windows (IIS) in order to be able to SET GLOBAL time_zone = 'Europe/Helsinki' (or whatever) the MySQL time_zone description tables need to be populated first.

I downloaded these from this link https://dev.mysql.com/downloads/timezones.html

After running the downloaded SQL query I was able to set the GLOBAL time_zone and resolve the issue I had where SELECT NOW(); was returning GMT rather than BST.

In my case, the solution was to set serverTimezone parameter in Advanced settings to an appropriate value (CET for my time zone).

As I use IntelliJ, I use its Database module. While adding a new connection to the database and after adding all relevant parameters in tab General, there was an error on "Test Connection" button. Again, the solution is to set serverTimezone parameter in tab Advanced.

If anyone is using GoDaddy Shared Hosting, you can try for following solution, worked for me.

When starting DB connection, set the time_zone command in my PDO object e.g.:

$pdo = new PDO($dsn, $user, $pass, $opt);
$pdo->exec("SET time_zone='+05:30';");

Where "+05:30" is the TimeZone of India. You can change it as per your need.

After that; all the MySQL processes related to Date and Time are set with required timezone.
