Time zone names

Hey chroma. How were you planning on identifying “home”? I've been able to think of at least four methods, each with drawbacks:

1. explicit picking from a list, which is more challenging than it initially appears;
   
2. waiting until you're in your home zone and then saying, here, this one now, which is more limiting than some might imagine (though technically savvy users could I suppose force the issue by temporarily overriding their phone's time zone selection);
   
3. having a picker for over on Gadgetbridge and then pulling the results over to the watch, which involves messing a lot with GB;
   
4. logging user behaviour and taking the one that's used most over an (eventually) extended period.
   
   

The last is both the hardest and the most magical (though I note there's a security implication if your watch is seized)…
