you need to provide all the needed information here, not just paste here a random link, furthermore your report does not indicate why is it wrong.
Hi Petr Baudis Well, this "random links" are the last two Bug reports I made concerning just this Bug, and I'm kind of getting tired to be "redirected" all the time... It is wrong because in Switzerland (where I live) the week starts on Monday and not on Sunday. Just like in en_GB or in de_DE, where it seems to be correct. If you need any further informations (besides the informations in the two random links, I mean), please ask, and I'll be happy to help.
It seems that Ulrich has changed this silently in 2010 by commit 8497559725cd067a60c4d6dbf34ff02b5be387d5.
