Timezone-related changes are not reflected in a jasperreport image running in an openshift environment

[selcuk9220]

By default, sequential file names by timestamp and timestamp pattern changes are not reflected on the "new schedule" screen.

Jasper report docker bitnami image : 7.5.0-debian-10-r43

I'm throwing the operations specified in the link below into the container by providing operations in the Dockerfile and app-entrypoint.sh file.

app-entrypoind.sh file
cp /jobModel.js /opt/bitnami/jasperreports/optimized-scripts/scheduler/model/jobModel.js 
OR
cp /jobModel.js /opt/bitnami/jasperreports/scripts/scheduler/model/jobModel.js
AND
export JAVA_OPTS="$JAVA_OPTS -Duser.timezone=Europa/Istanbul"
DockerFile
ADD ./jobModel.js /jobModel.js
OR 
COPY jobModel.js /opt/bitnami/jasperreports/optimized-scripts/scheduler/model/jobModel.js

After changing the relevant files, I am experimenting as follows. But after the container starts, the related files and the changes in it are reflected, but when the jasperreport stands up, I see that the change is not reflected. How can I overcome this situation? I couldn't find the solution.
