Demo of FileDateTime() returning partially-garbage result

The FileDateTime(path) function is supposed to return a string giving the modification date & time of a file.

In 4.0 it became broken.  It was working in 3.x.

Now you get results like "04/DD/YYYY 17:58:02"

For some reason the DD and YYYY are not replaced with values.

I will attach a trivial demo spreadsheet.  The code in the macro is as follows:

Sub MyMacro

  Dim path : path = "/etc/passwd"
  Dim d
  d = FileDateTime(path)
  MsgBox "FileDateTime(" & path & ") = """ & d & """"

End Sub
