What default timezone does Trello send with its REST API?

I’m unable to figure out what timezone Trello uses when sending data within their REST API. I don’t believe it is UTC (???).

Update:

According to this post: What timezone are dates in API data? - #2 by FredericMalenfant due dates are usually sent in the timezone of the card creator.

If so, I’m not sure how to figure out the certain user’s timezone, I’ve checked out what a member object is: https://developer.atlassian.com/cloud/trello/rest/api-group-members/#api-members-id-get

But I’m can’t find a time related property.

It looks like we give you a timezoneInfo from /1/members/me?fields=prefs:

{
  "id": "5589c3ea49b40cedc28cf70e",
  "prefs": {
    "timezoneInfo": {
      "offsetCurrent": 300,
      "timezoneCurrent": "CDT",
      "offsetNext": 360,
      "dateNext": "2022-11-06T07:00:00.000Z",
      "timezoneNext": "CST"
    }
  }
}
