Specifying timezone
The timezone for the container is set to GMT and I believe 1) maloja uses the system time 2) maloja does not have a setting to specify timezone (at the application level).
Could you update the dockerfile to overwrite the timezone if its passed through an environmental variable? I do this for an alpine base image on a container like this:
FROM ...
ENV TZ=Etc/GMT
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
...
