This bug may appear when the Linux system's timezone is set as a "named" timezone (like "America/Sao Paulo"). Switch the timezone to another, which is not named and has only the GMT code, like 'GMT+3'.
To do this, open up a terminal.
For Ubuntu/Debian type: sudo dpkg-reconfigure tzdata
In the menu that opens up, go down and choose "etc" and set right timezone code according to your location in GMT.

How do I solve this problem on OpenSUSE 13.2 ? I'm using Gnome 3

Settings -> Date and Time. Trying turning on/off Automatic time zone. If you have it off, you can change the time zone manually.
