This directory contains tools for time zone updates.
Data update tools
=================
download-iana-data.py
- A helper script run before update-tzdata.py.
It downloads the latest tzdata update from IANA and puts it in
the system/timezone/input_data/iana directory for use by the
update-tzdata.py script.
There are sometimes code and metadata changes associated
with tzdata updates that should be applied to ICU at the same time.
e.g. see http://bugs.icu-project.org/trac/search?q=2015d
update-tzdata.py
- Regenerates the ICU and libcore/bionic timezone data files.
ICU and CTS tests for bionic / libcore should be run before
and after.
