HRV intraday timezone

[nomida]

Hello, 

I would like to understand the response, this comes from  the fitbit example. 

{
  "hrv": [
    {
      "minutes": [
        {
          "minute": "20xy-10-wzT09:10:00.000",
          "value": {
            "rmssd": 26.617,
            "coverage": 0.935,
            "hf": 126.514,
            "lf": 471.897
          }

  ]
}

"minute": "20xy-10-wzT09:25:00.000",

is in UTC or current timezone? My guess is UTC, but how should I know the timezone and correct to make the assumption it was night or day?

Hi @nomida 

The timezone is user local time.   The date time values should coincide with the user's main sleep log.
