[tz-announce] 2022c release of tz code and data available

Aug. 16, 2022

      The 2022c release of the tz code and data is available.

This release reflects the following changes, which do not affect
timestamps unless your system has the awk bug mentioned below:

   Briefly:
     Work around awk bug in FreeBSD, macOS, etc.
     Improve tzselect on intercontinental Zones.

   Changes to code

     Work around a bug in onetrueawk that broke commands like
     'make traditional_tarballs' on FreeBSD, macOS, etc.
     (Problem reported by Deborah Goldsmith.)

     Add code to tzselect that uses experimental structured comments in
     zone1970.tab to clarify whether Zones like Africa/Abidjan and
     Europe/Istanbul cross continent or ocean boundaries.
     (Inspired by a problem reported by Peter Krefting.)

     Fix bug with 'zic -d /a/b/c' when /a is unwritable but the
     directory /a/b already exists.

     Remove zoneinfo2tdf.pl, as it was unused and triggered false
     malware alarms on some email servers.

Here are the GPG digital signatures for the release files:

PS. 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 DATAFORM=rearguard 
tailored_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'.
