It looks like MS.NET is marshaling DateTimes as an OLE Automation DATE (a
double) data type even for plain p/invoke DllImports.

The following cases are supported:

- DateTimes as method arguments
- DateTime fields inside a struct

Not supported are DateTime return types. Maybe because they are not needed for
COM interop.

A DateTime argument or field is converted to a "double". The value is set to
DateTimeInstance.ToOADate () and read back with DateTime.FromOADate (double).



Reproducible: Always
