the calendar widget for centos 7

[dusan]

Hello,

I have strange problem with the widget calendar in centos7. I am using KDE. My uname -r => 3.10.0-1062.9.1.el7.x86_64.

======================================================
My problem: I can install calendar widget without problems with actual correct date. But next days I see the same day data in calendar's box.
Where is the problem?

Thank you very much in advance.

Dusan
