This bug is fixed in 4.10.1, I'm filing it so it shows up in the list of fixed bugs. ktimezoned would only watch for changes to /etc/localtime if the file already existed. So if the file was not there and it gets created, nothing would happen. Reproducible: Always Steps to Reproduce: On a Fedora 18 installation with the fix for bug #315987 applied: 1. Visit System Settings->System Administration->Date & Time 2. Click on the Time Zone tab 3. Select a time zone different from the default (UTC) and hit Apply. Actual Results: The time zone jumps back to UTC, and closing the dialog asks whether to apply the changes (resetting the time zone to UTC) or discard the (bogus) changes. Expected Results: kcm_clock notices the changed time.
