Hello Support board!
I have tried to use sc.GetStartOfPeriodForDateTime function, but it always returns incorrect result.

Code is the following:



#include "sierrachart.h"

SCDLLName("Test")
SCString     MessageString;

SCSFExport scsf_Test(SCStudyGraphRef sc)
{
SCDateTime dtDayStartDateTime;
int    iYear;
int iMonth;
int    iDay;
int    iHour;
int    iMinute;
int    iSecond;

if (sc.SetDefaults)
   {
   sc.GraphName     = "Test";
   sc.FreeDLL     = 1;
   sc.AutoLoop     = 1;
   sc.ScaleRangeType = SCALE_SAMEASREGION;  
   return;
  }

if (sc.GetBarHasClosedStatus(sc.Index)!=BHCS_BAR_HAS_CLOSED)
{
   return;
}  
dtDayStartDateTime  = sc.GetStartOfPeriodForDateTime(sc.BaseDateTimeIn[sc.Index], TIME_PERIOD_LENGTH_UNIT_DAYS, 1, 0);  

dtDayStartDateTime.GetDateTimeYMDHMS(iYear, iMonth, iDay, iHour, iMinute, iSecond);  
MessageString.Format(" sc.Index = %d, Session Start time = = %.2d.%.2d.%d %.2d : %.2d ", sc.Index, iDay, iMonth, iYear, iHour, iMinute);
sc.AddMessageToLog(MessageString,0);   
}


Log looks as follow:

Chart: ESM3 30 min #1 | Study: Test | sc.Index = 0, Session Start time = = 01.01.1950 00 : 00 | 2013-04-12 09:49:25
Chart: ESM3 30 min #1 | Study: Test | sc.Index = 1, Session Start time = = 01.01.1950 00 : 00 | 2013-04-12 09:49:25

Chart: ESM3 30 min #1 | Study: Test | sc.Index = 3, Session Start time = = 01.01.1950 00 : 00 | 2013-04-12 09:49:25
Chart: ESM3 30 min #1 | Study: Test | sc.Index = 4, Session Start time = = 01.01.1950 00 : 00 | 2013-04-12 09:49:25
Chart: ESM3 30 min #1 | Study: Test | sc.Index = 5, Session Start time = = 01.01.1950 00 : 00 | 2013-04-12 09:49:25


Same output till sc.Index == 6000.

Theere is an old posts were similar problem with that function was described and as a resolution VC compiler were proposed to be used.

I've tried to compile it by Visual C++ Express, but result is the same.

Current version is 961.

Please advice how to make it working.
Thanks in advance and
