[luatex] Localisation of Lua or LuaTeX

[Ralf Meyer]

When I was trying out how to format the date in LuaTeX as advertised
using os.setlocale and os.date, I still got the english date.  Actually,
this is a Lua problem because when I run lua, I get the same result:

Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
> os.setlocale("de_DE")
> print(os.date("Heute ist der \%A im Monat \%B."))
Heute ist der Thursday im Monat March.
> os.setlocale("de_DE","time")
> print(os.date("Heute ist der \%A im Monat \%B."))
Heute ist der Thursday im Monat March.

What could be the reason for os.setlocale to have no effect?

Yours,
Ralf Meyer
