5.4.3.18 MaximumActualTime2
The MaximumActualTime2 Aggregate defined in Table 66 retrieves the maximum Good value for each interval as defined for MaximumActualTime except that Simple Bounding Values are included. The Simple Bounding Values for the interval are found according to the definition of Simple Bounding Values (see 3.1.9). Any Bad values are ignored in the computation. The Aggregate StatusCode will be determined using the StatusCode Calculation (see 5.3) for time based Aggregates. If a bounding value is returned then the status will indicate, Raw, Calculated or Interpolated.
If TreatUncertainAsBad is false and an Uncertain raw value is the maximum then that Uncertain value is used. Uncertain values are ignored otherwise.
If sloped interpolation is used and the End bound is the maximum value then End bound is used as the maximum with the timestamp set to the EffectiveEndTime of the interval. The End bound is ignored in all other cases.

| Use Bounds | Simple | |
| Timestamp | Time of maximum | |
| StatusCode Calculations | ||
|---|---|---|
| Calculation Method | PercentTime | |
| Partial | Set Sometimes If an interval is not a complete interval | |
| Calculated | Not Set | |
| Interpolated | Set Sometimes If an Interpolated bound is the Maximum | |
| Raw | Set Sometimes If a raw value is the Maximum | |
| Multi Value | Set Sometimes If more than one value is equal to the Maximum | |
| StatusCode Common Special Cases | ||
|---|---|---|
| Before Start of Data | Bad_NoData | |
| After End of Data | Bad_NoData | |
| No Start Bound | Treat the beginning value as Bad_NoData and compute the Aggregate | |
| No End Bound | Treat the ending value as Bad_NoData and compute the Aggregate | |
| Bound Bad | Use as value and compute the Aggregate as defined | |
| Bound Uncertain | Use as value and compute the Aggregate as defined | |
