java.sql.SQLException: The server time zone value xx time is unrecognized

Making a JDBC connection to the MySQL server with the latest mysql-connector-java:8.0.16 and hits the following SQLException:

Tested with

• MySQL 5.7
• Java 8
• JDBC driver, mysql-connector-java 8.0.16

	try (Connection conn = DriverManager.getConnection(
			"jdbc:mysql://127.0.0.1:3306/test", "root", "password")) {
		//...
	} catch (Exception e) {
		e.printStackTrace();

Output

java.sql.SQLException: The server time zone value 'Malay Peninsula Standard Time' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

1. Solution

1.1 Find the MySQL configuration file, for example, my.ini or my.cnf. Add a default time zone at the end of the file:

# Indicates the InnoDB Cluster Port.
# innodbclusterport=3306
# Load mysql plugins at start."plugin_x ; plugin_y".
# plugin_load
# MySQL server's plugin configuration.
# loose_mysqlx_port=33060
# Set default time zone
default-time-zone = '+08:00'

1.2 Restart MySQL service.

P.S Read this MySQL option files to find out where is the file (my.ini or my.cnf) located.

2. Solution

Alternatively, pass a serverTimezone property in the JDBC connection string directly.

	try (Connection conn = DriverManager.getConnection(
			"jdbc:mysql://127.0.0.1:3306/test?serverTimezone=UTC", "root", "password")) {
		//...
	} catch (Exception e) {
		e.printStackTrace();
