I am reading an xml file which has dates in yyy-mmddThh-nn-ssz which i understand is a standard format.

How can I get that into a tdatetime without parsing the the xml date myself?  Is there a function somewhere i can use?

Using Delphi 2010.

I think this is the solution for you...

function XmlDateTimeStrToDateTime(Str: string; ReturnUTC: Boolean):TDateTime

This is the function you should try (from http://www.delphigroups.info/2/1/248328.html)...

function XmlDateTimeStrToDateTime(Str: string; ReturnUTC: Boolean):TDateTime;
// '2004-06-08T00:00:00.0000000+02:00'
// '2004-06-08T11:47:00.0000000+01:00' // 11:47:00=LokalTid, 12:47:00=UTC
// '2004-06-08T18:47:58.0000000+01:00'
// '2004-06-08T18:47:58.0000000Z'
// ReturnUTC: False=returner lokal tid, True=returner UTC
var
  h, n, s: Word;
  p: Integer;
  Sfrac: string;
  V: Double;
  Code: Integer;
begin
  Result := XmlDateStrToDate(Str);
  p := Pos('T', Str);
  if p = 0 then
    Exit;
  Delete(Str, 1, p); // '11:47:00.0000000+01:00'
  h := StrToInt(Copy(Str, 1, 2));
  n := StrToInt(Copy(Str, 4, 2));
  s := StrToInt(Copy(Str, 7, 2));
  if h = 24 then
  begin
    Result := Result + 1;
    h := 0;
  end;
  Result := Result + EncodeTime(h, n, s, 0);
  Delete(Str, 1, 8); // '.0000000+01:00'
  // fractional seconds // '.0000000+01:00'
  if Copy(Str, 1, 1) = '.' then
  begin
    Delete(Str, 1, 1); // '0000000+01:00'
    p := 0;
    while (p < Length(Str)) and (Str[p+1] in ['0'..'9']) do
      Inc(p);
    if p>0 then
    begin
      Sfrac := '0.' + Copy(Str, 1, p); // '0.0000000'
      Delete(Str, 1, p); // '+01:00' eller 'Z'
      Val(Sfrac, V, Code);
      if Code = 0 then
        Result := Result + (V / SysUtils.SecsPerDay);
    end;
  end;
  // Nu har vi lokal tid
  if ReturnUTC then
  begin
  //Hvis der skal bruges
  // timezone // '+01:00' eller 'Z'
    if Copy(Str, 1, 1) = 'Z' then
      Exit;
    if (Copy(Str, 1, 1) = '-') or (Copy(Str, 1, 1) = '+') then
    begin
      h := StrToInt(Copy(Str, 2, 2));
      n := StrToInt(Copy(Str, 5, 2));
      s := 0;
      if (Copy(Str, 1, 1) = '-') then
        Result := Result + EncodeTime(h, n, s, 0);
      if (Copy(Str, 1, 1) = '+') then
        Result := Result - EncodeTime(h, n, s, 0);
    end;
  end;
end;

You should have TXSDateTime in your run-time library.

How To Reduce Deployment Times With Pre-Baked AMIs

Even if we can't include all the files in the base image, we can sometimes include some of the larger files that we would otherwise have to download, and we can also sometimes remove the most time-consuming steps. This can help a lot with reducing deployment times.
