got =
    array.from(
        rows: [
            {_time: 2021-01-01T00:00:00Z, _measurement: "m", _field: "t", _value: 1.2},
            {_time: 2021-01-01T01:00:00Z, _measurement: "m", _field: "t", _value: 0.8},
            {_time: 2021-01-01T02:00:00Z, _measurement: "m", _field: "t", _value: 3.2},
        ],
    )

want =
    array.from(
        rows: [
            {_time: 2021-01-01T00:00:00Z, _measurement: "m", _field: "t", _value: 1.2},
