On my brand new N9, my contacts' birth dates are automatically imported from my Skype account, but for some reason, they appear one day earlier in the N9's Contacts application or in the specific calendar.
Just to be clear, I'm not talking about the notification for the birthday event, but for the actual contact's birthdate.
My timezone (i'm in France) is correctly set in both my N9 settings and my skype account.

I wouldn't be worried too much about this, except I believe it is responsible for syncevolution not wanting to sync with my owncloud instance anymore.

Has anyone else experienced this ?
Is there a way to disable birth dates import from skype contacts ?
Is there a way to remove a contact information that has been imported from skype ?
Any other idea ?
