All, I am facing some strange issue, I believe its due to my ignorant, would appreciate if you can help me out on this: DB Server system OS CentOS. I have loaded the timezone tables in mysql using: mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql After loading, I have restrated the DB using systemctl restart mariadb: Then I have tried below in DB: select @@global.time_zone,@@system_time_zone; [image: Inline image 1] SELECT CONVERT_TZ( NOW(), @@global.time_zone , 'UTC' ), UTC_TIMESTAMP; [image: Inline image 3] SELECT CONVERT_TZ( NOW(), @@system_time_zone , 'UTC' ), UTC_TIMESTAMP; [image: Inline image 4] SELECT CONVERT_TZ( NOW(), 'EDT' , 'UTC' ), UTC_TIMESTAMP; [image: Inline image 2] For some reason, If I use named TZ in CONVERT_TZ function for FROM_TZ, its always showing NULL. Can anyone help me out what else i can do so I can pass the abbreviation or named TZ in FROM_TZ. Regards, Karthick
