This really is a question about where does the Phantom get its timezone info from. This could be done as has been suggested based on the PC clock that the assistant is on. I would be interested to see if in addition to timezone, the daylight savings time (DST) profile is taken account of. These can be fiddly to apply on an international product. Even where DST is defined it can still have exceptions. For example Arizona I believe has regions which do their own thing.
Great question - not silly.
More easily and accurately implemented in Naza firmware using very simple business logic and polygons as has been done with no fly zones.
Yes good point, though this is a lot harder to do with DST.
