Time
Parameters
the model element id of the response or counter
the name of the counter or response
the replication that the period was within
the number of the period, numbered consecutively starting at 1
the time that the period started
the length of time associated with the period
the collected value. For Response and TWResponse instances the value property represents the average of the response over the indicated period. For Counter instances the value property represents the total count during the indicated period. The value is null only when an observation-based Response was not observed at all during the period, in which case there is no average to report. A TWResponse always has a value, because a period in which it never changed still has its height across the whole period, and a Counter always has a count.
