Well.... someone went ahead without asking here first ;)
Of course creating a KLocale instance might be expensive, so the solution
of creating one instead of switching the global one should probably only
be done when the other klocale can be kept somewhere and reused (like
in kspread).

Sorry, the parameter isn't the language, but the instance name...

// Do this once when first needed
KLocale englishLanguage(KGlobal::instance()->instanceName());
englishLanguage.setLanguage( "en_US" );  // or "C"

// Then do this to format a date in english
QString dateInEnglish = englishLanguage.formatDate(qdate);

[still untested though ;)]

It's setLanguage("pl"). The string to use is the language as known in l10n/.
