Date & Time in System settings doesn't saves NTP-server address

[Gannet]

Trying to add other time-server in Date & Time applet results nothing. I'm checking the box near the Time Server and entering new server address, then pushing the Save button. But it doesn't saves anything: server address disappears and check box is clears.
Also system time is differs to several hours instead of real. I've tried to correct it by hand but it changes after some time again to several hours back. Also error window sometimes appears trying to save time settings. Please, see attachment.

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
