Display a date in different locales

Display a language/locale friendly version of New Year's Day for 2009 for several languages/locales. E.g. for languages English, French, German, Italian, Dutch the output might be something like:

Thursday, January 1, 2009
jeudi 1 janvier 2009
giovedì 1 gennaio 2009
Donnerstag, 1. Januar 2009
donderdag 1 januari 2009

(Indicate in comments where possible if any language specific or operating system configuration needs to be in place.)

Display the current date and time

Create a Date object representing the current date and time. Print it out.
If you can also do this without creating a Date object you can show that too.
use Class::Date;
my $date = Class::Date->now();
print $date->string()."\n";

print localtime()."\n";
use Time::Piece ();

# Date object
my $date = Time::Piece::localtime;
print "$date\n";
# no object
print scalar(localtime),"\n";
