I'm running Fedora 45 with KDE Plasma 6.7.1, and the system clock repeatedly changes to one hour ahead of the correct time. Switching the date and time settings from automatic to manual and back temporarily fixes it, although KDE reports that the date and time application has crashed. The clock soon becomes incorrect again. Each time I change the setting, the application also asks for my password twice, even when the first password entry is accepted. I'm in the UK, where the timezone observes daylight saving time (BST), and I'm not dual-booting with Windows or another operating system. What could be causing this, and how can I fix it?

Since you’re not dual-booting, Windows changing the hardware clock is unlikely to be the cause. Because you’re in a daylight-saving timezone, check that Fedora is using the correct zone—probably Europe/London—and that only one time-synchronization service is managing the clock. Running `timedatectl` should show the current timezone and whether network time synchronization is active. You can also try setting the zone explicitly with `sudo timedatectl set-timezone Europe/London`, then restart the time-sync service.
I’m only running Linux, so there isn’t a Windows installation changing the clock. The system is in the UK, where the timezone switches between GMT and BST.
