Details:
RFC 8536 defines 3 formats for tzfile. NSTimeZone only knows about version 1,
and reports bad data without error when dealing with version 2+. I tracked
down this patch because I discovered SOGo have been wrecking gmtoffset for
years.
Attached is a patch that implements enough of version 2 so that NSTimeZone can
report correct gmtoffset with a version 2+.
I had to change trans from int32_t to int64_t in the interface. I guess it
could break other code. If that is better, I can refactor the code to ignore
transitions that do not fit in in32_t.
