I understood your dilemma, just had no meaningful contribution.
Now that I ponder it, forget DST and just consider timezones. If you can find a stretch of coast vs islands that's bifurcated by a timezone, what's the ideal answer you'd want to see? (Forget for a moment that timezones are probably designated to avoid this scenario).
The GPS clearly recognizes the precise line along which the timezone changes. Tidal level at two locations, only 50 yards between them, must be identical. But the time at each location differs by one hour. How would you want the GPS to inform you .... prolly with a line for the timezone? Otherwise, the Skipper wouldn't know WHAT the darn thing is doing! And just as significant, the Skipper wouldn't know when he has changed zones. (not to be confused with the fourth mode under sail!)
Now complicate this scenario with daylight savings differences, which are subject to jurisdictional changes. What would you like to see on the screen? And is it realistic for the map-maker to manage it?
Maybe zulu IS best! Then it is the Skipper's job to interpret his offset from Greenwich ...
