FormatSettings.ShortDateFormat not the same as System Locale

Question

 _FormatSettings := TFormatSettings.Create(GetThreadLocale);

No, you should not replace the slashes in TFormatSettings.ShortDateFormat. That could cripple the date formulation.

procedure DateTimeToString(var Result: string; const Format: string; DateTime: TDateTime; const AFormatSettings: TFormatSettings);

in System.SysUtils
