Issue Summary

• When a Jira site's default timezone is configured under the default time zone using the URL https://your-site/jira/settings/system/general-configuration, the JSM Operations > Global Policies time slot does not consistently reflect the configured timezone.
• Instead, the backend appears to normalize timezones sharing the same UTC offset/DST rules to a single canonical identifier

Steps to Reproduce

1. Configure the timezone to (GMT-05:00)Toronto here: https://your-site/jira/settings/system/general-configuration
2. Check the JSM operations > Global Policy and see that the timezone is defaulted to: ((GMT-04:00) America/New_York EDT - Eastern Daylight Time)

Expected Results

• The policy time slot should display the same timezone identifier that the admin configured as the site default

Actual Results

• The policy time slot displays a different but offset-equivalent timezone identifier instead of the configured site default.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
