Question

Timezone shown as 'IST (Interpreted as Asia/Jerusalem)' on Admin Dashboard > Information even though all system components are set to Asia/Kolkata. Ticket timestamps display incorrectly.

Accepted Answer

Set the MariaDB/MySQL server timezone to UTC by adding default-time-zone = +00:00 under [mysqld] in the MariaDB config file (e.g. /etc/my.cnf.d/mariadb-server.cnf) and restarting the database. This resolves the display and timestamp mismatch. The IST label is a known display-only mapping quirk in class.timezone.php and jstz.min.js for the Kolkata timezone; no official fix is planned for the current codebase.
