[PROPOSED PATCH 2/2] Use lz format for new tarball

Please, do not use xz for a new distribution format. The xz format is defective. See for example http://www.nongnu.org/lzip/xz_inadequate.html or the note in the third xz test at the bottom of http://www.nongnu.org/lzip/lzip_benchmark.html If a format that 7-Zip can handle is desired, I recommend bzip2 which produces a tzdb tarball a 25% smaller than gzip and only a 9% larger than lzip.

tzdist and tz@iana
by Alexander Belopolsky Sept. 8, 2016

On Wed, Sep 7, 2016 at 4:04 AM, Jon Skeet <skeet(a)pobox.com> wrote: > (Then there's tzdist of course, but that's a whole other matter...) I have been looking at RFC 7808 (aka tzdist) and I wonder what is the relationship between the proposed distribution standard and this project. While RFC 7808 mentions "Olson" as a possible "primary-source", it does not look like the proposed JSON format is capable of carrying all information provided by Olson raw files. The distribution format looks like a text variant of the binary zoneinfo files, but it is not clear whether or not the distributed data includes timezone abbreviations. Are there any plans to support the tzdist format in tzcode? Will IANA run its own "Time Zone Data Server"?
