I've been testing Tidycall, and while I like its design, there's one thing I don't quite understand: time zones. I'm working for a client based in Venezuela, but they book appointments internationally, specifically in Europe and the US. My issue is this: when I enable the booking type settings and select my client's working hours (e.g., 8:00 am to 12:00 pm and 2:00 pm to 5:00 pm), how should the booking calendar be displayed to an international client, given the time difference between countries? I want to avoid affecting my client's established working hours.
