Curious to know what ended up happening for you and what you found out as I'm headed to AUS at the beginning of next month (Feb 4th and my flight arrives in Melbourne on the 6th. I have a decent layover in LA on the 4th). When I leave I will have a 340+ day streak going (660 calories/day) and I don't want to lose it! I've given this a lot more thought than I probably should have and I think I've devised a plan and hoping it works (I posted over on reddit and got one confirmation that it will work but still unsure).
My big concern, similar to your first question, is that upon the time change forward to AUS it will pull head activity into the next day. My only thought is to do my first day's workout when my timezone (EST) and Australia are on the same day so if it pulls it ahead, the exercise & activity rings will just be later in the day (so, I would have to do it between 3am and 7:30am before departing). I realize that with this plan, I will likely miss my stand ring for the 4th and 5th but I'm OK with that as I had to miss one due to an issue updating my watchOS a few months back... Anyway, my plan is as follows:
- To start, my phone is set to automatically set time based on location
- On the day of the 4th, I fill my activity ring before leaving home and for the airport my watch registers the activity for the day of the 4th based on EST (and would also be registered on the 4th if I was in AUS as well).
- Upon arriving into LAX (before turning airplane mode off), I turn Date and Time to Manual and set to Australia, thereby getting my watch and phone to think it is the 5th.
- I fill my activity ring for the 5th by doing a workout from the airport during my layover
- I leave LAX and continue to let my phone think I'm on Australia time
- I land in Australia on the 6th and hit the gym sometime that day to fill my rings on the 6th
- At this point I can switch my phone back to auto set date and time
