    Bug in retrieving relative timestamps (start/endtime) greater than *-7d from PI Trend

    imuehlenhoff

      Hi,

       

      i have a .NET Addin which access PI Trends and saves start and end Time (same behavior with VBA). I access start and End Time via the properties of a trend symbol.

       

      When the user selects a relative start time bigger than exactly *-7d i get back absolute timestamps. The processbook show the correct relative time in the define trend window

       

       

       

      For example User sets Starttime: *-7d / Endtime *

       

      myTrend.Start and Endtime are exactly what the user set

       

       

       

      For example User sets Starttime: *-8d / Endtime *

       

      myTrend.Start: "21.01.2014 10:19:12,212" and Endtime is: "29.01.2014 10:19:12,212"

       

       

       

      The limit seems to be exactly 7 days, no matter if specified as days, minutes etc.

       

      How this can be avoided? how can i get relative timestamps exactly like shown in the trend definition?

       

       

       

      Regards
