Comment 6 for bug 1445577

The bug seems only to occur when you do not alter the time when you edit the entry.

1. Create new entry by tapping in the calender app.
2. Edit the entry and set a new time -> the entry is at the correct time.
3. Edit again and do not change the time -> the entry jumps 2 hours back in time (I am at UTC + 2)
After the entry jumped you can edit the entry without jumping again. At least as long as you not change the time.

When you edit the time again, the entry is at the correct time. But if the entry is edited afterwards without modifying the time, the entry jumps 2 hours back in time.
