Steps to Reproduce

Scenario 1

1. Install Jira with Microsoft SQL as the database

3. Set your user's timezone to Chicago
4. Add a version with a release date to a project.
5. Change profile time zone to New York and check on the release to see it is now a day behind

3. Add a version with a release date to a project.
4. The release date is behind 1 day.
5. Changing the user profile to the same as the System Timezone. The release date still behind 1 day. Also, it does not honour the user profile timezone changes.

Workaround

Scenario 1:

• Set the timezone of every user to match the Jira default 

Scenario2:

• Set the Default user time zone back to the System Default timezone (the same timezone matching with the jvm.system.timezone ) via Administration > General Configuration > Edit settings.
  You can find the timezone for "jvm.system.timezone" via Administration > System Info.
