Feature idea - update phone's time zone based on flight time

It would be nice to have the option on the mobile phone application to offer updating of the phones time zone setting based on the flight destination.

E.g. I like to update my watch and the phone after take off so I get used to the times at the destination airport and more importantly I track the right time if there is a connecting flight to catch.

I’m aware that flight aware is not just for tracking flights by flying passengers so this feature will have to be added as an option.

This would need to be a feature of your OS, since changing the phone timezone setting is not something that applications have access to.
