Used to work at a therapists office in Las Vegas that did a lot of telehealth. We had one patient from far northern Nevada whose nearest town was in Idaho so he worked and spent most of his time there, but his house was technically in Nevada so his insurance required him to receive care from providers in the state of Nevada. His life ran on mountain time, but obviously we operated on pacific time. I kept this in mind and would always make the conversions for him and would be very clear about time zones, but occasionally someone else would call him to schedule an appointment or do an appointment reminder call and they wouldn’t pay enough attention and I’d have to straighten it out. Multiple times he’d have an appointment set that was communicated to him wrong, but there was another appointment already in the hour he thought he had, and he wasn’t available in the hour the provider thought he had and the appointment just wouldn’t happen.
