Cal.com + GPT + Make — booking time “3pm tomorrow” shifts to 10am (timezone issue)

Hi Guys! I’m having a bit of a problem.
I took a template online, it has TWO scenarios.

Scenario 1, it checks for avaability.
However.

When I talk to my AI Agent on Retall AI, it ends up like this.
Does anyone know why my agent does this?

Some more informatioN!

The Workflow is on Make.Com I’ll attach a photo.
