The range() function filters records based on time bounds.
Each input table's records are filtered to contain only records that exist within the time bounds.
Records with a null value for their time are filtered.
Each input table's group key value is modified to fit within the time bounds.
Tables where all records exists outside the time bounds are filtered entirely.
Function type: Transformation
*Output data type: Object
range(start: -15m, stop: now())

Specifies the oldest time to be included in the results.
Relative start times are defined using negative durations. Negative durations are relative to now. Absolute start times are defined using timestamps.
Data type: Duration or Timestamp
