Yes. I don't think that the standard locales package provides en_SE, so you are free to add one (with the proviso that it might get deleted when you upgrade any package that thinks it owns the locale directories).
Just copy a suitable starting point, say en_DK, edit it to make it say what you want, then recompile as above subtituting en_SE for en_GB in my instructions. You would need to copy the whole of the output directory produced instead of just the LC_TIME part. You may find that some non-GTK X applications complain about your locale though. Normally this means that they will defauilt to the "C" locale. You may need to do some more investigation. You might also try to get en_SE added to the locales package. -- calendar - week starts on the wrong day for locale https://launchpad.net/bugs/2098 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
