Time is displaying differently after migrating from Server to Cloud

Summary

After migrating from Server to Cloud, the time is showing differently in "Page History" tab due to the JVM timezone. This is similar issue as in Jira: JRACLOUD-65305.

Environment

• Server to Cloud migration

Steps to Reproduce

1. In Confluence Server, make sure the user timezone is not set / has been set to other than UTC
2. Perform a space export
3. Import the backup into Confluence Cloud
4. Compare the "Published" time in Page History between Server and Cloud

Expected Results

The time is showing the same as Confluence Server

Actual Results

The time is showing 8 hours late (taking UTC+8 as the example)

Notes

If -Duser.timezone is not set, it will take the system timezone.

Workaround

Set the user.timezone to UTC

1. Under <installation-directory>/bin/
2. Edit setenv.sh
3. Add the timezone property:

   CATALINA_OPTS="-Duser.timezone=UTC ${CATALINA_OPTS}"
