Description mkamp 2017-03-26 19:23:20 UTC

I tried to create an appointment in my calendar as a reminder to set some old clocks manually to daylight-saving time. 
My timezone is CET / CEST or Europe/Berlin.

When setting the start time to 02:00 on the last sunday in march, the end time fields were empty instead of the expected value start-time +1h ... On another try the end date suddenly was 01.01.1970... I also couldn't finish the dialog, klicking the Okay-Button just did nothing.

It took some time until I realized that the point in time I wanted to address simply doesn't exist: The clock jumps from 01:59 to 03:00 in this night. <facepalm />

---
Expected Behaviour:
When I klicked the Okay-Button, an error message would have been helpful to explain what I was missing. This might also a nice place to hide an easter egg ;-)
---

P.S.:
I did not check what happens if you try this on the last Sunday in October when every minute between 02:00 an 03:00 is doubled?

Someone has reminded me that this bug still exists and I just tried to reproduce it on Kubuntu. I'm happy to see that it was fixed in the meantime: Now korganizer complains that I tried to set an invalid start date. :-)
