时间格式

1、

var
  fmtSettings: TFormatSettings;
  dt: TDateTime;
begin
  Memo1.Lines.Add(DateTimeToStr(Now));
  Memo1.Lines.Add('');

  GetLocaleFormatSettings(GetUserDefaultLCID, fmtSettings);
  Memo1.Lines.Add(fmtSettings.ShortDateFormat);
  Memo1.Lines.Add(fmtSettings.ShortTimeFormat);
  Memo1.Lines.Add(fmtSettings.LongDateFormat);
  Memo1.Lines.Add(fmtSettings.LongTimeFormat);
  Memo1.Lines.Add(fmtSettings.ThousandSeparator);
  Memo1.Lines.Add('');

  
  fmtSettings.DateSeparator := '/';
  fmtSettings.TimeSeparator := ':';
  fmtSettings.ShortDateFormat := 'yyyy/mm/dd';
  fmtSettings.ShortTimeFormat := 'hh:nn:ss';
  dt:= StrToDateTime('2010/3/19 08:09:10', fmtSettings);
  Memo1.Lines.Add(DateTimeToStr(dt));
  Memo1.Lines.Add('');

  fmtSettings.DateSeparator := '/';
  fmtSettings.ShortDateFormat := 'yyyy/mm/dd';
  fmtSettings.TimeSeparator := ':';
  //fmtSettings.ShortTimeFormat := 'hh:nn:ss';
  Memo1.Lines.Add(DateTimeToStr(dt, fmtSettings));
  Memo1.Lines.Add(DateTimeToStr(now, fmtSettings));
end;

 

2、输出：
