Sorry, I was wrong: "rm /etc/localtime && ln -s /usr/share/zoneinfo/Europe/Prague /etc/localtime" did not help.. after restart the time was UTC again...
"cat /etc/default/rcS | grep UTC" gives "UTC=no" "show UTC" option of applet is unchecked, zone is Europe/Prague (UTC+1) but clock applet still shows UTC when synchronization is enabled -- clock applet shows UTC time not timezone time when NTP used https://launchpad.net/bugs/15514 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
