Timestamp between Jetappointment(crocoblock) using a webhook and Google Calendar is not working properly

Hi,
Today, I connected JetAppointment to Google Calendar via webhook, which worked. However, the appointment is entered in Google Calendar 2 hours later.
For example, appointment: 13:15,
appointment in Google Calendar: 3:15 p.m.

Question: The time zone is Europe (Zurich).

  1. How do I adjust the settings so that the correct time zone is entered in Google Calendar?
  2. For the time entry, I would like to have 24 hours, i.e. 13:15 and not 1:15 p.m.

Thank you for your help, Gregor
