I changed the timezone via Gnome settings -> System -> Date & Time. I observed the wrong time in the Gnome clock on top of the screen when the Bratislava timezone was selected. Date command and timedatectl displayed correct data. See attached screenshots: [image: Bratislava TZ - wrong time displayed.png] [image: Prague TZ - the right time displayed.png] The problem with Gnome clock on top of the screen occurs also when timezone is changed via command dpkg-reconfigure tzdata
