API created meetings have wrong start time

Hi

This morning I made two API calls to create Zoom meetings but the meetings weren't created with the specified start time. The start time seems to have been set to the meeting created time.

Call 1 was made to the endpoint: https://api.zoom.us/v2/users/i0....................BA/meetings
with the body:

{
    "agenda": "",
    "default_password": true,
    "duration": 30,
    "start_time": "2026-07-09T07:00:00Z",
    "timezone": "Europe/London",
    "topic": "Another test"
}

And it got this response:

{
  "uuid": "...............==",
  "id": 9.............5,
  "host_id": "i0...............BA",
  "host_email": "ad..............uk",
  "topic": "Another test",
  "start_time": "2026-07-09T09:54:38Z",
  "duration": 30,
  "timezone": "Europe/London",
  "created_at": "2026-07-09T09:54:38Z",
  ...
}

Call 2 had the same problem. I haven't seen this behaviour before.

Any advice would be appreciated.
