Hi, The correct time is already set in the Guacamole container, as shown in the screenshot below.
[cid:[email protected]] I have mounted my VM’s timezone volumes into the container, and it is correctly set to Europe/Paris. [cid:[email protected]] However, when I check my logs and use the guac_time variable, the time is still shown in UTC.

I’ve tried updating the time in all three containers (Guacamole, PostgreSQL, Guacd) and also changed the timezone inside PostgreSQL, but nothing has worked so far. I haven’t been able to find any guidance online. The guidance is here: https://guacamole.apache.org/doc/gug/configuring-guacamole.html#parameter-tokens Could you tell me where this variable gets its time from? This should be coming from the time zone of the guacamole container. After you change the local time zone of the container you will likely need to restart the container or the Tomcat process in the container, as I suspect the change is only re-read at startup. -Nick
