Customers register for a webinar on a specific date, and receive a confirmation for a different date

API Endpoint(s) and/or Zoom API Event(s)
To create a webinar at zoom - /users/{userId}/webinars
to add registrants to an existing Zoom webinar - /webinars/{webinarId}/registrants?occurrence_ids=Webinar_UUID__c

Description
We use the above Zoom API’s to create a Zoom webinar and to register people for those webinars. Customers will register for the webinar using our web based portal and through the Zoom API Call we will register this on Zoom side and a registration conformation email will be sent to the customer.
The customers are receiving a confirmation for a different date instead of the registered date.

We have checked in Salesforce and the we are passing the correct webinar start date time at the time of creating a webinar using Zoom API Callout.
