Yeah, that makes sense for a 3-minute call, a small drift usually isn’t a problem, especially if it’s just for calendar bookings. The simplest way is to pass EST from your backend at the start. If you want full accuracy, you could refresh it every minute or so, and that would cover longer calls without relying on the model to convert time. Also, for Google Calendar, you can either set the timezone on the event or use a small conversion tool so everything stays consistent in EST avoids any mix-ups with UTC. We can discuss this more privately, and I can walk you through a setup that handles both the prompt and calendar reliably. @mango
