Latex problem with \today [closed]

I have a problem with the \today statement in Latex. As you can see below I'm getting the wrong result for the German date format which would be 17. November 2016.

The gloss-german.ldf defines it in the right order:

\def\date@german{%
\def\today{\number\day.%
\space \ifcase\month%
\or\if@austrian@locale Jänner\else Januar\fi\or Februar\or März\or%
April\or Mai\or Juni\or Juli\or August\or September\or Oktober\or%
November\or Dezember\fi
\space \number\year}%
}


You may try his with the following code:

%!TeX program = xelatex
\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage[spelling=new]{german}
\setotherlanguage{arabic}
\begin{document}
German (\textgerman{Deutsch \today})
\end{document}


Here my output:

Thanks for your help and sorry for my English.

• Welcome to TeX.SX! I get the correct date with XeLaTeX and an error with LuaLaTeX (undefined \luatexpardir, package luatex85 does not help). – Heiko Oberdiek Nov 17 '16 at 22:59
• I tried this with two different computers and it did't work. Strange. I tried now with TeXworks and recieved the correct date but in Texstudio it doesn't work. Any idea why? – Mathnix Nov 17 '16 at 23:01
• @HeikoOberdiek luatex commands are enabled unprefixed so it'll be \pardir something needs updating... – David Carlisle Nov 17 '16 at 23:05
• This might due to bidi. Can you tell what version of it you have? – egreg Nov 17 '16 at 23:07
• I'm voting to close this question as off-topic because the issue was solved by a software update – egreg Dec 24 '16 at 12:29
