I have specified everywhere that we are operating in London/Europe timezone. Yet there is still an hour gap between what the agent sees between my calendar and the real time. It will book at 3pm and it shows up at 4pm on the calendar. It will say 3-4pm is available when it is not

Suggestion: Double-check that the

timeZone

field is explicitly set to

"Europe/London"

in your Google Calendar tool configuration when creating or checking events. For example:

json
{
  "startDateTime": "2025-06-08T15:00:00",
  "endDateTime": "2025-06-08T15:30:00",
  "timeZone": "Europe/London"
}

This ensures all bookings and availability checks align with your intended timezone and prevents the 1-hour offset issue.

Ensure both availability checks and event creation explicitly pass timeZone: "Europe/London" in ISO format, and use Make.com’s parseDate() and formatDate() to handle time correctly, this will eliminate the 1-hour time shift caused by UTC vs local time confusion..
