Bug 906972

I have a possible fix for that too, but I need some sleep now, I'll do builds after sleeping.

From bug #906854:

Well spotted, that's exactly what is happening. After selecting the new timezone the dialogue box whites out and when it comes back I find UTC is still selected, even though 'date' shows the new timezone.

Can you please test this build:

?

(If you're testing on a live image, don't forget to also apply the kde-workspace fix from bug #906854.)

You probably need to restart your session after updating the package, so that the fixed ktimezoned actually gets started.

OK, tested and working. The dialogue correctly sets and keeps the new timezone. Thanks Kevin.

There is still a (relatively minor) issue which I hadn't noticed earlier. After applying a timezone change and proceeding to exit the dialogue, you still have to confirm Apply or Discard. Selecting Apply simply exits (leaving the change in place), but Discard does the same thing, i.e. it doesn't revert the change. IIRC in other Settings dialogues hitting Apply before exiting means you don't have to reconfirm, so the question doesn't arise. At the same time, making a change and attempting to exit without hitting Apply will bring up the confirmation dialogue with the expected semantics. IOW the Time/Date is inconsistent with this behaviour.

These comments still apply as of 4.9.5-7 (F18). IMHO the easiest fix is to disable the confirmation when the user has already hit Apply in the settings dialogue. This would be consistent with other settings dialogues.

kde-runtime-4.9.5-2.fc18 has been pushed to the Fedora 18 stable repository.  If problems still persist, please make note of it in this bug report.
