Answer 1

Excel has no built-in date/time data type. In Excel, date/times are formatting options for the double data type. You can declare an Excel-DNA function as taking a DateTime parameter to have the passed-in doubles converted to DateTime automatically, or you can do the conversion yourself using DateTime.FromOADate() (since the Excel double encoding matches the COM/OLE date implementation).
