Bug#987747: Acknowledgement (TAG: kclock -- a convergent app that works in both Plasma Desktop and in Plasma Mobile. KClock is very similar to GNOME Clocks: it has regional clocks, timer, stopwatch and alarms.)

[Transparent Wing]

Also, just to note: currently, there are KTimer, Kronometer, KAlarm, KTeaTime. 
If you use chronometer, alarms and timer, you'll need to install 3 different 
programs. Also, the interface of KTimer and KAlarm is not practical to manage 
alarms. Adding KClock to the official repos would be very handy!
