My message disappeared. I've determined this was because I changed my primary email address and wasn't recognized as subscribed to the list, but it would have been nice to have received a notification of this as I have for other lists. On Thu, Oct 29, 2015, at 16:14, Paul Eggert wrote:
Sorry, I must be missing something, but I am not following the question. For that absolute transition, there's no difference between 02:00 standard time, 03:00 local time, and 08:00 UTC; they're all the same thing, and the "s" in "2:00s" is purely for convenience in the source data.
The binary data does include information about the difference for the purpose of determining how the transition should be treated if the timezone is transposed to a different offset due to being used as the basis for interpreting POSIX rules. This data is in the sections which tzh_ttisgmtcnt/tzh_ttisstdcnt determines the size of.
