Thanks for your detailed information. It turns out that the bug only occurs
when the start-of-day setting is not midnight.

Now fixed in 4.14 branch (commit a791b69599c3571ff2f4b1cc9033d8fb30f1bc33) -
although bear in mind that there are unlikely to be any further official KDE
4.14 releases.
Also fixed in 15.12 branch (commit fd5960c66c650ef42207e83b44e80e6e243474dd),
for release 15.12.2.

[kalarm] [Bug 346060] KAlarm calculates deferred alarm time wrongly

Hi, David! Thanks for your interest in this bug.

I've just tested it again and the bug is still there. I have the same KAlarm
version as reported previously.
I tied to test it with one-time alarm. I set one display alarm to trigger in
several minutes. It did and I successfully deferred it for several more
minutes. Time calculation was correct. Then I tried to reproduce the bug with
repeating alarm with repeating interval in days.
These are the steps I took;
1. File, New, New Display Alarm (Ctrl+D)
2. Type some display text
3. "At date/time" set to today and checked "Any time"
4. On Recurrence tab I set Daily and Recur every 15 days 
5. After clinking OK, alarm immediately pops.
6. I chose Defer and defer it for 15 hours and 17 minutes, so that it time
boxes above it displays that the alarm should trigger tomorrow at 3 a.m.
7. When I press OK the main KAlarm window shows that the alarm will trigger
tomorrow at 1 p.m. - IT ADDED 10 HOURS.

Furthermore (I just discovered this). After restarting KAlarm and opening main
window, this alarm (previously set for 1 p.m.) was now set to 8 a.m. - it
returned back 5 hours! I'm really puzzled. :)
After repeated restart it stays at 8 a.m.

My suggestion is to check calculation of deferred time for DATE-ONLY alarms. In
my KAlarm settings for "start of day for date-only alarms" I set 5:00. I guess
that that KAlarm added 5 hours to 3 a.m. that I wanted. Main window also added
the same amount, but it only was reflected to display of alarms. After restart
in effect was only first 5 hours added.

After changing "start of day for date-only alarms" to 06:00, main KAlarm window
displayed 3 p.m. and after restarting it got back to 9 a.m. - 6 hours added to
3 a.m. that I wanted.

Please try taking the same steps I took. I'm pretty sure you'll will reproduce
this bug, as I tried everything: deleting data and similar.

Regarding your questions:
- I haven't expresses myself correctly. The system is set to CET (GMT+1). Clock
applet has three time zones set, but I guess it's only relevant to the clock
applet.
- Time zone in KAlarm is same as system time zone (Europe/Sarajevo)
- No, I didn't edit the alarm. I just deferred it, and check if it was set
correctly.
- I will add the attachment so you can examine the calendar and KAlarm
settings.

I'm sorry this bug has been overlooked. If possible, can you provide more
information on this:

- You say that in KDE you have two time zones. How are these set? (In System
Settings, you can only set one time zone, and that sets it for the system.)

- What time zone is set in KAlarm (in the KAlarm menu, go to Settings ->
Configure KAlarm -> Time & Date).

- What do you mean by pressing OK in the main alarm window? Did you bring up
the alarm edit dialog after deferring the alarm, edit it and click OK?

- Can you please attach a copy of KAlarm's calendar (usually in
~/.kde/share/apps/kalarm/calendar.ics), after deferring the alarm. Please say
what time is then shown for the alarm in KAlarm's main window.
