A small feature request for db<>fiddle.
Running this query on [db<>fiddle](https://dbfiddle.uk/?rdbms=mysql_8.0&fiddle=1af1fc4e0a1b5ce267fe2d9d82595ace) returns NULL:
SELECT CONVERT_TZ(NOW(), 'Europe/Dublin', 'America/Los_Angeles') AS conv;
The null here is (probably) caused by not loading the [IANA](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List) time zones as outlined [here](https://dev.mysql.com/doc/refman/8.0/en/time-zone-support.html#time-zone-installation).
Compared with [db-fiddle.com](https://www.db-fiddle.com/f/dGLPHQFjAP17pUe1rGYyjn/0)

This is potentially useful functionality for anyone who has to deal with timezones - db<>fiddle offers an OFFSET functionality (see last snippet in fiddle above) but this does not take into account DST (Daylight Savings Time) which can be important.
Should you require any further details or clarification and/or input, please don't hesitate to let me know.
Thanks for pointing this out and including a link for how to resolve the issue. This is now fixed for all active versions of MySQL and MariaDB.
