Get file date & hour from NMFTP

This is POSIX date convention: for date less 7 month ago
the date be reflected as mon day time
(have in mind current year),
for greater date  format is mon day year.

For decode this date you can try following


const
  Months: array[1..12] of string = (
    'Jan', 'Feb', 'Mar', 'Apr',
    'May', 'Jun', 'Jul', 'Aug',
    'Sep', 'Oct', 'Nov', 'Dec');

function MyDecodeDate(S: String): TDateTime;
var
  Parser: TParser;
  StringStream: TStringStream;
  Month, Day, Year, Hour, Minute: Integer;
  d,m,y: Word;

  function GetMonth: Boolean;
  begin
    Month := 1;
    while not Parser.TokenSymbolIs(Months[Month]) and (Month < 13) do Inc(Month);
    Result := Month < 13;
  end;

begin
  StringStream := TStringStream.Create(S);
  try
    Parser := TParser.Create(StringStream);
    with Parser do
    try
      if not GetMonth then
        raise EConvertError.Create('');
      NextToken;
      Day := TokenInt;
      NextToken;
      Year := TokenInt;
      NextToken;
      if Token = ':' then
        begin
          Hour := Year;
          DecodeDate(Date, y, m, d);
          Year := y;
          NextToken;
          Minute := TokenInt;
          Result := EncodeDate(Year, Month, Day) + EncodeTime(Hour, Minute, 0, 0);
        end
      else
        Result := EncodeDate(Year, Month, Day);
    finally
      Parser.Free;
    end;
  finally
    StringStream.Free;
  end;
end;

I read the code and it seems to work but... what is TParser??

Sorry i found Tparser in classes unit.
I will select your comment as an answer but i need some advice first...
what will happens when the year changes... i still get the new year (says 2002) but the real year will be (2001)???
Thanks
