AF SDK Summaries question

Hello Fellow SDK developers:

I have a strange issue with a PIPointList.Summaries() result, the last value's timestamp is wrong.

I have attached a word doc that shows the debug screen, below is the code:


                    var span = AFTimeSpan.Parse(timespan + spanUnit.ToString());

                    var points = PIPoint.FindPIPoints(serv, lstVesselTagNmes);

                    var pointList = new PIPointList(points);



                    // Results should be sent back for 10000 tags in each page.

                    var config = new PIPagingConfiguration(PIPageType.TagCount, 10000);

                    var listAvgResults = pointList.Summaries(myTimeRange, span, type,

                        AFCalculationBasis.TimeWeighted, AFTimestampCalculation.Auto, config);

                    List<AFValues> afValues = listAvgResults.Select(pointResults => pointResults[type]).ToList();



                    foreach (var pointValues in afValues)


The timespan is set to 1 hr.

The time range is 9-mar-17 13:26 to 16-mar-17 13:05

First AFValue = 9-mar-17 13:26

Last Value = 16-mar-17 11:26

Where is 12:26???

It is clearly in the data archive.

The issue is that it seems to happen randomly.


Any suggestions would help!
