Stop time of aggregation

Each measurement is taken to represent an interval of duration equal to the sampling interval (In this data set, the sampling interval is 10 seconds). This attribute represents the time of day of the end of the interval represented by the last measurement in the aggregation. This attribute represents only an exterior limit of time period, not any internal gaps.
