var
success: Integer;
json: TChilkatJsonObject;
dt: TCkDateTime;
bLocal: Integer;
dtObj: TDtObj;

begin
success := 0;

//  Parse Microsoft JSON Dates (AJAX Dates)
json := TChilkatJsonObject.Create(Self);

success := json.Load('{ "AchievementDate":"/Date(1540229468330-0500)/"}');

dt := TCkDateTime.Create(Self);
success := json.DateOf('AchievementDate',dt.ControlInterface);
if (success <> 1) then
  begin
    Memo1.Lines.Add('Unable to parse a date/time.');
    Exit;
  end;

//  Show the date in different formats:
bLocal := 1;
Memo1.Lines.Add('RFC822: ' + dt.GetAsRfc822(bLocal));
Memo1.Lines.Add('Timestamp: ' + dt.GetAsTimestamp(bLocal));
Memo1.Lines.Add('YYYY-MM-DD: ' + dt.GetAsIso8601('YYYY-MM-DD',bLocal));

//  Get integer values for year, month, day, etc.
