Aside from what Jon Skeet asked, you should also indicate what you used to generate the tz binary files (tzdata only has the source for the info, not the binary versions you're obviously looking at - and quite properly I think.) Was it the zic that is with the 2015f sources, or did you use some other version, and if so what? What platform was that running on? | This causes the TimeZoneInfo parsing code to throw an exception because it | is assuming these transitions are sorted in ascending order. That's reasonable, they should be. | Is this an intentional change in the tzfiles? No, what you're seeing is definitely a bug. The issue is how that happened. kre
