PostgreSQL timezone error with DbSchema

I want to setup my postgreSQL server to 'Europe/Berlin' but having an error:

SET time zone 'Europe/Berlin';
ERROR:  invalid value for parameter "TimeZone": "Europe/Berlin"

But the real issue is with DdbSchema, when I want to connect to my DB i've got the error

FATAL: invalid value for parameter "TimeZone": "Europe/Berlin"

DbSchema works when I connect to my local db but not with my NAS (Synology) DB.

Any idea ?

Solution

Found a way to solve the problem:

You have to start java with the proper time zone.

In my case, my server is GMT, so i had to add the args -Duser.timezone=GMT
