How to on open Writer document form Date Field display current date

How to on open Writer document form Date Field display current (OS) date? (The document is opened from template.) I can set “Default date” but it’s static date. I’d like to provide current date to document user so she/he can leave it or change it.

Thanks to Villeroy[Solved] Date Field can’t set date I managed to set it via macro:

Sub SetDefaultDate(ByVal DateFieldName As String)
	oForm = ThisComponent.drawpage.forms(0)
	oElm = oForm.getByName(DateFieldName)

	strDigits = CDateToIso( Date() )
	oDate = createUnoStruct("com.sun.star.util.Date")
	oDate.Year = cInt(left(strDigits,4))
	oDate.Month = cInt(mid(strDigits,5,2))
	oDate.Day = cInt(right(strDigits,2))
	oElm.Date = oDate
End Sub

Sub TestSetDefaultDate
   SetDefaultDate("Date Field 1")
End Sub
