Does the customer see the available time slots converted into his own time zone? For example, if I am in New York and my customer/student is in Shanghai, and I am available Monday-Friday, 7:00 a.m. to 11:00 a.m., will the customer see available times slots for Monday-Friday morning, 7:00 a.m. to 11:00 a.m., or will he see available time slots for Monday-Friday evening, 7:00 p.m. to 11:00 p.m.?
