Enable Multiple Time Zone Selection

In your appointment flows, when you set the Show Time Zone Pick List attribute to True, the appointment time slot pages show a dropdown list with all the time zones supported in Salesforce. When scheduling appointments, users can select the time zone in which they want to see the appointment time slots.
