Yeah that's fair, but that's purely a UI/display problem and there is and cannot be any solution that works without context.

Ultimately, if you don't like it, tell your calendar to show it differently.

In one timezone, yes.

Apperently you want the times to be shown for when you will be in that timezone. But the calendar doesn't know when you will be in what timezone, and it's such a rare thing that apparently no one made a calendar where you can day "I'll be (mentally) in this timezone from that day and then in that timezone a week later".

So you, your last sentence is right, because that's impossible. That's different from "hard".
