Another answer to this occurred to me. The time zones are
not mapped at anywhere near the level of accuracy of GPS. In some
places, even in the US, the time zone boundaries follow political borders that
are not reliably defined even at a level of five or ten arcseconds in
lat/lon. I suppose they could put in a feature that says "time zone changing
somewhere around here" maybe displaying two zone times within a few hundred
yards of the boundary.
I wonder if cell phone companies actively seek locations for their towers
so that their cells do not straddle time zone boundaries...
