Päivämäärä pdf-tiedoston nimeen makrolla

Teen Calcista pdf-tiedostoja macrolla, mutta miten saisi tiedostonimeen päivämäärän?

Sub Main

End Sub

sub pdf
rem ----------------------------------------------------------------------
rem define variables
dim document as object
dim dispatcher as object
rem ----------------------------------------------------------------------
rem get access to the document
document = ThisComponent.CurrentController.Frame
dispatcher = createUnoService("com.sun.star.frame.DispatchHelper")

rem ----------------------------------------------------------------------
dim args1(1) as new com.sun.star.beans.PropertyValue
args1(0).Name = "URL"
args1(0).Value = "file:///C:/Nimeton201.pdf"
args1(1).Name = "FilterName"
args1(1).Value = "calc_pdf_Export"

dispatcher.executeDispatch(document, ".uno:ExportDirectToPDF", "", 0, args1())


end sub
