Anyone know how Garmin has things programmed to determine the proper time zone when you use "Set Time With GPS?" I've found an issue with HAST here in the Pacific not being delineated properly it looks like. I should be in UTC -10 here at 18deg30min North, but my watch is trying to tell my I'm in UTC -11. According to the accepted time zone boundaries, I should have entered into Hawaii-Aleutian Standard time at 15deg North. Is there a file that can be tweaked to fix this in the system?
In that situation, I'd be tempted to turn off Sync with GPS, and let the watch pick up the time from your phone (which in turn typically picks up the time from your cellular network operator).
That’s typically what I do. As a ship captain time zones are fairly ambiguous during transits, but I’m sure there are some pleasure boaters around Hawaii that could get fouled up by this if they aren’t paying attention.
