Hello perl experts,
I run Munin on a Debian server. In the graphs the days of the week are
displayed in German. Now I monitor the weather data on a raspberry,
which basically works, but the days of the week are displayed in
English. How do I get this Perl script to display the weekdays in
English?

# CGI script to create image using RRD graph
use CGI qw(:all);
use RRDs;

The output of locale is the same for both computers:
