If I understand the issue correctly, then what you have described is about right. :)  It's an issue that I'm not very familiar with, so some of the details might be slightly off (or might not be!) but your overall understanding of it certainly seems good to me.

"If I decide to keep one of my devices in PDT while I'm in Europe, I should not use HabitRPG on that device until everything's back on the same timezone... make sure that everything's checked off or greyed out before I get on my long flight" -- Yes, those two ideas should keep you safe.
