I don't know if something changed, but the behaviour of sc.GetStartOfPeriodForDateTime does not seem to be consistent with the documentation when using TIME_PERIOD_LENGTH_UNIT_WEEKS. Documentation says: For periods based on weeks, the start will be either Sunday or Monday depending upon the setting of Global Settings >> General Settings >> General >> Data >> Use Monday as Start of Week instead of Sunday.
and yet, it seems to return the date time for Saturday.if I include the code below and step through in the debugger, I can see that the AddDays part is executed, which it shouldn't be if the week start is Sunday. auto sDT = sc.GetStartOfPeriodForDateTime(sc.BaseDateTimeIn[sc.ArraySize - 1], TIME_PERIOD_LENGTH_UNIT_WEEKS, 1, 0); if (sDT.IsSaturday()) sDT.AddDays(1); Maybe it is a misunderstanding on my part? |
