Unity calendar indicator shows wrong days for Evolution events

[Valdisvi]

Ubuntu 12.04, Evolution 3.2.3.
Unity calendar indicator shows wrong days for Evolution events.
My timezone is EEST (Riga, Latvia), and events what are scheduled in Evolution in Wednesday and Thursday (as Google calendar events) in Evolution are shown as in Tuesday and Wednesday (-1 day) accordingly.
See attached picture.

Probably it is because of wrongly set locale see https://bugs.launchpad.net/localization-lv/+bug/993505

I suppose I should have added a translation, the bug #993505 is about glibc mistakenly setting Sunday as the first day of week for LC_COLLATE=lv_LV even though like in everywhere else in Europe week of course starts on Monday. Whether that could cause this bug, I'm not so sure about. Also regarding that bug, it was filed against vanilla glibc shipped with Gentoo and no one has verified that the bug affects Ubuntu too.

Status changed to 'Confirmed' because the bug affects multiple users.

Same thing for me in Sweden.

I can confirm this problem with Ubuntu 12.04 LTS 64-Bit (3.2.0-36-generic # 57-Ubuntu SMP) and Evolution 3.2.3. I'm located in Germany and the events in the Unity Evolution Calendar Indicator have the wrong dates (-1 day of the real events).
