else
//2. Reading from a OpenXml Excel file (2007 format; *.xlsx)

I had to use the Boolean flag for converting dates both when creating the reader and extracting the data set. When I did this it worked.

.
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(file.InputStream, true);

excelReader.IsFirstRowAsColumnNames = true;
DataSet result = excelReader.AsDataSet(true);
