t

Gives access to the datapoint’s timestamp

Every datapoint in a stream has a timestamp. This timestamp is hidden when performing operations in PipeScript, since all operations are performed on a datapoint’s d (data) field. To permit processing based upon timestamps in PipeScript, the t transform exposes the datapoint’s timestamp.

Remember that raw datapoints are in the form:

[
  {
    "t": 123456.23,
    "d": 4,
    "dt": 0
  }
]

When performing transforms, d==4 will return true, since we operate on the “d” (data) field. But the timestamp is 123456.23, so the transform t will result in the following datapoint:

[
  {
    "t": 123456.23,
    "d": 123456.23,
    "dt": 0
  }
]
