Duration: Calculates either duration of all events initiated in the output period .

...

Transformation:	Duration
Transformation Group:	Events
Description:	Calculates either the net duration or the gross duration of the events initiated in the output period. An event in this transformation is defined as a the largest possible series of subsequent subevents where the duration of gaps (where there are no subevents) is shorter than the specified maxGapDuration parameter. A subevent is defined as a measurement in time in the input where the value is larger than the specified threshold parameter. The duration of a single subevent is equal to the duration of the input time step. The duration of an event is the sum of the duration of its subevents plus the duration of the gaps that do not exceed the maxGapDuration parameter, and is registered only in the output period where the event initiated.

...

Purpose and use of Transformation:	This transformation can for instance be used to report on the duration of sewer spillage events for each month.
Background and Exceptions:	The input must be per second (for instance m3/s). The output time step must be bigger than the input time step. All input values must be non-missings, otherwise the result will be set to missing value. In case one of the inputs is doubtful, the output flag is set to ORIGINAL_DOUBTFUL.

...

input Equidistant measurements in units per second (for instance m3/s).
