Hi,

For those people who like to decompose the TDateTime object as it is returned by Time and iTime into something useful in C++ use the following calls to convert this COledatetime object into something civil:
Code:



SYSTEMTIME mytime;
VariantTimeToSystemTime( iTime(symbol, timeFrame, iUp+1), &mytime);

Now mytime is a structure the details can be found here:

http://msdn.microsoft.com/en-us/library/ms724950%28v=vs.85%29.aspx
Code:

typedef struct _SYSTEMTIME {
  WORD wYear;
  WORD wMonth;
  WORD wDayOfWeek;
  WORD wDay;
  WORD wHour;
  WORD wMinute;
  WORD wSecond;
  WORD wMilliseconds;
} SYSTEMTIME, *PSYSTEMTIME;


Hope this helps others to make the conversion, took me way to long to figure this out.

Wessel
