# I recently had to try to update the TZDB of a JDK installation where I could not install lzip
# from any registered package repository and trying to compile lzip from source was failing.
# I discovered that as an alternative to using the tzdb-latest.tar.lz file I could just use both
# the tzcode-latest.tar.gz and the tzdata-latest.tar.gz to generate the needed rearguard tarballs.
# These instructions have been updated to no longer rely on lzip since it's not available out of
# the box in many environments.

# SHORTCUT ALERT: If you don't want to go through the whole process to build the rearguard tarball
# or use the ziupdater tool to generate and install a tzdb.dat file you can always just download
# the latest tar.gz and tzdb.dat files from a repo I created that automatically builds new TZDB
