Comment 1 for bug 583679

This is because he didn't enter the setting like the script asks him to.

To use the first language of the week as Monday, the script asks the user to enter his locale using this format (example): "en_GB.UTF-8" - but the user has to enter it manually. The script then writes the LC_TIME value in the locale file (this is the only value the script writes to that file - nothing else it changed).

As you can see from his locale file, instead of entering it_IT.UTF-8, the user only entered "it.UTF-8" - that's why the LC_TIME is set to "LC_TIME="it.UTF-8"" and since the value is wrong, the system used the default language - English.

Therefore it's not a bug in the script but the user didn't read the instructions correctly...
