[fpc-devel] Behavior of conversion between vardate variants and string in fpc and delphi

Point 3 sounds to me as best and logical.

This code in DelphiXE:

   ShortDateFormat := 'dd#mm#yyyy'; // the problem occurs regardless of 
the format option
   DateSeparator:='#';
   V := '20#04#2011';
   v1:=varAsType(V, varDate);
   D:=v1;
   Writeln('Date: ' + DateToStr(D));

Outputs:
Date: 20#04#2011

So it seems, that DelphiXe also uses ShortDateFormat, DateSeparator
