What conclusion should we make looking at this long table? I am unsure 
concerning difference from content of tzdata package (IANA or Olson DB) 
that is rather standard on Linux. Emacs uses it though libc (API has 
some limitations, but conversion from UTC to local time should be 
accurate). Various programming languages have libraries to use this 
database.

I can not say anything concerning Windows besides that I have seen 
tables for mapping of tzids to IANA timezones.
