If you are planning to travel to another state or country where time zone is different, and you want to start booking appointments in advance, you can fix your timezone for your available slots and start getting bookings.
For example, if you are traveling from San Fransisco to Sydney from 5 Jan to 15 Jan, and you are available to schedule meetings between 10:00 AM to 5:00 PM AEDT (Australian Eastern Daylight Tim). You can create a new event template for all dates that you are in Sydney and fix your timezone to AEDT.
Here is how:
Step 1: Create Appointment Type
Step 2: Click on "Edit Appointment Type"
Step 3: Click on "Change Hours" and locate option "Availability hours are in fixed time zone".
All available times will be in AEDT. Meetings you will schedule also will be according to Australia time. This way you can start getting meetings in correct timezone even before your travel starts with this feature.
