README.zoneinfo

testdata/zoneinfo contains time-zone data files that may be used with CCTZ.
Install them in a location referenced by the ${TZDIR} environment variable.
Symbolic and hard links have been eliminated for portability.

On Linux systems the distribution's versions of these files can probably
already be found in the default ${TZDIR} location, /usr/share/zoneinfo.

New versions can be generated using the following shell script.

  #!/bin/sh -
  set -e
  DESTDIR=$(mktemp -d)
  trap "rm -fr ${DESTDIR}" 0 2 15
  (
    cd ${DESTDIR}
    git clone https://github.com/eggert/tz.git
    make --directory=tz \
        install DESTDIR=${DESTDIR} \
                DATAFORM=vanguard \
                TZDIR=/zoneinfo \
                REDO=posix_only \
                LOCALTIME=Factory \
                TZDATA_TEXT= \
                ZONETABLES=zone1970.tab
    tar --create --dereference --hard-dereference --file tzfile.tar \
        --directory=tz tzfile.h
    tar --create --dereference --hard-dereference --file zoneinfo.tar \
        --exclude=zoneinfo/posixrules zoneinfo \
        --directory=tz version
  )
  tar --extract --directory src --file ${DESTDIR}/tzfile.tar
  tar --extract --directory testdata --file ${DESTDIR}/zoneinfo.tar
  exit 0

To run the CCTZ tests using the testdata/zoneinfo files, execute:

  bazel test --test_env=TZDIR=${PWD}/testdata/zoneinfo ...
