Timezone selection in scheduled trigger does not show current UTC offset

I could reproduce the problem in the latest build

What happened?

When creating scheduled deployment or runbook triggers, users can select a time zone and the local time for the trigger.

The timezone dropdown displays the UTC offset and the corresponding timezone name.

These offsets are based on the base time zone offset and do not reflect the current time zone's adjustments. For example, during daylight saving time, the UTC offset is for the standard time instead of daylight saving time.

Note: The created deployment triggers take daylight saving time into consideration.

Reproduction

1. Create a scheduled deployment/runbook trigger
2. Select a time zone that is currently observing daylight savings
3. Observe that the time zone is showing the UTC offset for the standard time
4. Wait for the deployment/runbook to be triggered
5. Observe that the deployment/runbook run occurred at daylight saving time

Workaround
