Start by running the reported khal new 30/06/2025 09:30 10:30 Europe/Helsinki Another Event :: with Alice and Bob command, then inspect the result with khal interactive. Trace how the command parses the end time and time zone, and consider the issue done when the event is timed, uses Europe/Helsinki, retains Another Event as its title, and shows the expected start and end.
