Change MySQL Timezone on Amazon RDS_MySQL

Amazon RDS doesn’t allow you to change timezone, It keeps same UTC time zone across all regions. time_zonevariable in the parameter group is read only.

You can change the time zone on each connection or session by making a procedure in default mysql database and call this function on each init connection.

1. Create a procedure for IST

DELIMITER | CREATEPROCEDURE mysql.rds_store_time_zone ()IFNOT(POSITION('rdsadmin@'INCURRENT_USER())=1)THEN SET SESSION time_zone ='+5:30';ENDIF|DELIMITER ;

2. Update parameter group

aws rds modify-db-parameter-group --db-parameter-group-name parameter_group_name --parameters "ParameterName=init_connect, ParameterValue=CALL mysql.rds_store_time_zone, ApplyMethod=immediate"

3. Grant execute permission

GRANT EXECUTE ON PROCEDURE mysql.rds_store_time_zone TO 'user'@'%';
