How to get dicom time tag

Support
1

I need to get the dicom generation time after loading a series of dicom files and I think the dicom tag is 0008|0033. But I couldn’t find a function to solve this.

int main()
{

	string OpenPath = "C:\\Users\\26327\\Desktop\\dll4sw\\data\\SE4\\";
	
	
	vtkSmartPointer<vtkDICOMImageReader> reader =
		vtkSmartPointer<vtkDICOMImageReader>::New();
	reader->SetDirectoryName(OpenPath.c_str());
	reader->Update();
	
	// clinic info
	double* PixelSpacing = reader->GetPixelSpacing();
	double* DataSpacing = reader->GetDataSpacing();
	float* ImageOrientation = reader->GetImageOrientationPatient();
	float* Position = reader->GetImagePositionPatient();
}
