I live in Alabama not too far from the Tennessee state line. Over the past 6 months I have driven across the Tennessee state line at three very different places. Every time I do the GPS time changes by about 30 mins.
The issue is obviously not a timezone setting, since the timezone line is not crossed and the time doesn't change by a exact hour. It seems to me that there is something setup for Tennessee to have a different time, but I don't understand why that would be.
Has anyone else seen anything similar?
Where could I find any files that may include timezone data for each state?
