Right now Confy does not support timezones: if a timezone is defined in pentabarf or ics, it's dropped and date are considered in current system timezone.

To be correct, the timezone should be considered, and the user should have the option to change the timezone used to show all date/times. (eg, the event is New York timezone, but I'm following it online from Milan, I could have an option to show dates and times in "event timezone", "my current time zone" or "a specific timezone")
