The 2020c release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Briefly: Fiji starts DST later than usual, on 2020-12-20. Changes to future timestamps Fiji will start DST on 2020-12-20, instead of 2020-11-08 as previously predicted. DST will still end on 2021-01-17. (Thanks to Raymond Kumar and Alan Mintz.) Assume for now that the later-than-usual start date is a one-time departure from the recent pattern. Changes to build procedure Rearguard tarballs now contain an empty file pacificnew. Some older downstream software expects this file to exist. (Problem reported by Mike Cullinan.)

If your tzdata parser does not yet support negative DST offsets or times past 24:00, or if it insists on a 'pacificnew' file that is no longer present, this release's data entries can be turned into a rearguard-format tarball that should work even with these older parsers. This is intended to be a temporary transition aid for these parsers. To generate a rearguard-format tarball, obtain the full distribution as described above, and run the command 'make rearguard_tarballs' on a development host. Or you can run 'make rearguard.zi' to generate a single file that can be fed directly to a parser that works like 'zic'.
