All,
Sorry for the off-topic post, but I'm fishing.
I'm one of the maintainers of vzic, a utility to convert IANA tzdata into iCalendar VTIMEZONE components. In the process of tweaking the tool to handle recent tzdata changes and to generate more correct/compact VTIMEZONEs in "pure" mode, I managed to break the generation of Outlook-compatible VTIMEZONEs.
Just an idea: Is it possible that the conversion started to fail for newer TZDB versions which support switching time *back* for DST, and have a 25 hour number in some rule(s)? Can the "rearguard" versions of TZDB still be converted?
