\label{Course_Prefs_Language}
This panel lets you adapt the language and date format of your course:
\begin{itemize}
\item Language used: whatever you set here overrides both user and institutional settings, i.e., it forces a certain interface language on all users in the course.
\item Timezone: allows you to set the timezone in which the course runs, which overrides the timezone of your institution.
\item Locale: influences how dates are displayed.
\end{itemize}
