So that you can update the UI to show the new time zone? Or change the time format to indicate that it’s no longer in the same time zone as the user is in? That’s just off the top of my head, I’m sure there’s more.
I agree that it would be a nice feature, but I'd really have to be scraping the bottom of the feature barrel before I got to this. Unless my product heavily featured scheduling, or was a clock.
