Date and Time Conventions

Is there a convention out there which states when a flight switches to "destination time"? We are flying back from NYC on VS4 and somewhere over the ocean we will move on a day and it will become our wedding anniversary. I'd like to know when I could mark the occasion....

Thx

Well the VS04 departs at 18:00 NYC time = 23:00 UK time so an hour into the flight = midnight UK = wedding anniversary !

Provided you don't divert ... ):

It's my understanding that in the cockpit, all flight times are noted as GMT around the world - this ensures that all flight crew on every aeroplane are in sync. with each other - stand to be corrected!

In which case, you could use that convention?

Yes - in aviation and in the military, GMT is used, although it is referred to as Zulu (the various timezones have letter designations, and GMT happens to be Z).

Using GMT/Zulu seemse the best idea...

Thanks all!

It's an interesting question from a passenger perspective. I used to alter my watch soon after take-off and then stare at it trying to persuade myself that I believed it.

But yes, I agree that in your case you should go by UTC because it gives you an excuse to celebrate ASAP.
