My KAlarm version:
Version 2.11.2-5ak
KDE Frameworks 5.15.0
Qt 5.4.2, kompiliert gegen 5.4.2)
Das xcbFenstersystem

My OS: Ubuntu 15.10, 64 Bit

My version of KAlarm starts at Login which is fine. Only, each time I am disturbed by the following message:

“Time zones are not accessible: KAlarm will use the UTC time zone. (The KDE time zone service is not available: check that ktimezoned is installed.)”

I have activated the option: “Don't show this message again” but it still continues showing up every time. I don't mind if KAlarm uses the UTC time zone. Nevertheless I would be very grateful if you could let me know how I can get rid of the warning message once and for all.

Further information:
-The set time zone in my Ubuntu system settings is “Berlin” and that is correct.
-I do not have any service or process called timezone or ktimezone running or set in my OS.
-In my KAlarm under Settings → Configure KAlarm → Time and Date → Time zone, the only option available is UTC.
-I do not have any Plasma workspace installed on my System.

Thank you for investigating this bug.

Reproducible: Always

Steps to Reproduce:
1.Install Kalarm
2.Configure the settings so that Kalarm starts at login
3.Reboot your OS
4.When the Kalarm Timezone warning appears: Check the box so that the Kalarm Timezone warning will not be shown again
5.Reboot your OS and see that the warning is there once again

Actual Results:  
The following warning message is displayed: "Time zones are not accessible: KAlarm will use the UTC time zone. (The KDE time zone service is not available: check that ktimezoned is installed."
There is a box to be checked if one does not wish to see the above message again. Checking the box does not change anything.

Expected Results:  
I would expect that activating the option "not to see this message again" should put a definite end to the permanent showing up of this warning each time a boot my OS.
